Pigment colors: Alizarin crimson

From Wikipedia:
Alizarin or 1,2-dihydroxyanthraquinone (also known as Mordant Red 11 and Turkey Red) is an organic compound with formula C14H8O4 that has been used throughout history as a prominent dye, originally derived from the roots of plants of the madder genus.

Alizarin was used as a red dye for the English parliamentary New Model Army. The distinctive red color would continue to be worn for centuries (though also produced by other dyes such as cochineal), giving English and later British soldiers the nickname of "redcoat". In 1869, it became the first natural pigment to be duplicated synthetically.

Alizarin is the main ingredient for the manufacture of the madder lake pigments known to painters as Rose madder and Alizarin crimson. The term is also part of the name for a variety of related dyes, such as Alizarine Cyanine Green G and Alizarine Brilliant Blue R, and gave its name to alizarin crimson, a particular shade of red. The word derives from the Arabic al-usara "juice".

Occurrence
Alizarin occurs in the root of the common madder (Rubia tinctorum) and in various parts of Indian madder (Rubia cordifolia).

History
Madder has been cultivated as a dyestuff since antiquity in central Asia and Egypt, where it was grown as early as 1500 BC. Cloth dyed with madder root pigment was found in the tomb of the Pharaoh Tutankhamun and in the ruins of Pompeii and ancient Corinth. In the Middle Ages, Charlemagne encouraged madder cultivation. It grew well in the sandy soils of the Netherlands and became an important part of the local economy.

By 1804, the English dye maker George Field had refined the technique to lake madder by treating it with alum, and an alkali, that converts the water-soluble madder extract into a solid, insoluble pigment. This resulting madder lake has a longer-lasting color, and can be used more efficaciously, for example by blending it into a paint. Over the following years, it was found that other metal salts, including those containing iron, tin, and chromium, could be used in place of alum to give madder-based pigments of various other colors. This general method of preparing lakes has been known for centuries.

In 1826, the French chemist Pierre-Jean Robiquet found that madder root contained two colorants, the red alizarin and the more rapidly fading purpurin. The alizarin component became the first natural dye to be synthetically duplicated in 1868 when the German chemists Carl Graebe and Carl Liebermann, working for BASF, found a way to produce it from anthracene. About the same time, the English dye chemist William Henry Perkin independently discovered the same synthesis, although the BASF group filed their patent before Perkin by only one day. The subsequent discovery (made by Broenner and Gutzhow in 1871) that anthracene could be abstracted from coal tar further advanced the importance and affordability of alizarin's artificial synthesis.

The synthetic alizarin could be produced for a fraction of the cost of the natural product, and the market for madder collapsed virtually overnight. The principal synthesis entailed oxidation of anthraquinone-2-sulfonic acid with sodium nitrate in concentrated sodium hydroxide. Alizarin itself has been in turn Structure and properties
Alizarin is one of ten dihydroxyanthraquinone isomers. Its molecular structure can be viewed as being derived from anthraquinone by replacement of two neighboring hydrogen atoms (H) by hydroxyl groups (-OH).

It is soluble in hexane and chloroform, and can be obtained from the latter as red-purple crystals, m.p. 277–278 °C.

Alizarin changes color depending on the pH of the solution it is in, thereby making it a pH indicator.

Applications
Alizarin Red is used in a biochemical assay to determine, quantitatively by colorimetry, the presence of calcific deposition by cells of an osteogenic lineage. As such it is an early stage marker (days 10–16 of in vitro culture) of matrix mineralization, a crucial step towards the formation of calcified extracellular matrix associated with true bone.

Alizarin's abilities as a biological stain were first noted in 1567, when it was observed that when fed to animals, it stained their teeth and bones red. The chemical is now commonly used in medical studies involving calcium. Free (ionic) calcium forms precipitates with alizarin, and tissue block containing calcium stain red immediately when immersed in alizarin. Thus, both pure calcium and calcium in bones and other tissues can be stained. The process of staining calcium with alizarin works best when conducted in basic solution.

In clinical practice, it is used to stain synovial fluid to assess for basic calcium phosphate crystals. Alizarin has also been used in studies involving bone growth, osteoporosis, bone marrow, calcium deposits in the vascular system, cellular signaling, gene expression, tissue engineering, and mesenchymal stem cells.

In geology, it is used as a stain to indicate the calcium carbonate minerals, calcite and aragonite

Wednesday!

I know I keep promising that I'm going to get back to a daily schedule of posts, and I know that weeks have gone by and there's been nothing regular about my schedule!

And I apologize! Stuff happens, abetted, I admit, by procrastination. There was a helluva lot of scanning of material I needed to do which I never did, and now I've got to get all that material back where it came from, so I've got 2 days of probably 12 hours a day spending my time scanning, and double checking to make sure I havne't missed any pages, etc.

So I'm going to spend the next 2 days doing that, will be all caught up on Wednesday, and will resume daily posts here.

And will finally have learned my lesson about procrastination - don't do it!

John Singer Sargeant

John Singer Sargent (January 12, 1856 – April 14, 1925) was an American artist, considered the "leading portrait painter of his generation" for his evocations of Edwardian era luxury. During his career, he created roughly 900 oil paintings and more than 2,000 watercolors, as well as countless sketches and charcoal drawings. His oeuvre documents worldwide travel, from Venice to the Tyrol, Corfu, the Middle East, Montana, Maine, and Florida.

An American expatriate who was trained in Paris prior to moving to London, Sargent enjoyed international acclaim as a portrait painter, though not without controversy and some critical reservation; an early submission to the Paris Salon, his Portrait of Madame X was intended to consolidate his position as a society painter, but it resulted in scandal instead. From the beginning his work was characterized by remarkable technical facility, particularly in his ability to draw with a brush, which in later years inspired admiration as well as criticism for a supposed superficiality. His commissioned works were consistent with the Grand manner of portraiture, while his informal studies and landscape paintings displayed a familiarity with Impressionism. In later life Sargent expressed ambivalence about the restrictions of formal portrait work, and devoted much of his energy to mural painting and working en plein air.

Early life
Before Sargent's birth, his father FitzWilliam (b. 1820 Gloucester, Massachusetts) was an eye surgeon at the Wills Eye Hospital in Philadelphia 1844-1854. After John's older sister died at the age of two, his mother Mary (née Singer) suffered a breakdown, and the couple decided to go abroad to recover. They remained nomadic expatriates for the rest of their lives.

Though based in Paris, Sargent's parents moved regularly with the seasons to the sea and the mountain resorts in France, Germany, Italy, and Switzerland. While Mary was pregnant, they stopped in Florence, Italy because of a cholera epidemic. Sargent was born there in 1856. A year later, his sister Mary was born. After her birth, FitzWilliam reluctantly resigned his post in Philadelphia and accepted his wife's entreaties to remain abroad. They lived modestly on a small inheritance and savings, living a quiet life with their children. They generally avoided society and other Americans except for friends in the art world. Four more children were born abroad, of whom only two lived past childhood.

Though his father was a patient teacher of basic subjects, young Sargent was a rambunctious child, more interested in outdoor activities than his studies. As his father wrote home, "He is quite a close observer of animated nature." His mother was quite convinced that traveling around Europe, and visiting museums and churches, would give young Sargent a satisfactory education. Several attempts to have him formally schooled failed, owing mostly to their itinerant life. Sargent's mother was a fine amateur artist and his father was a skilled medical illustrator. Early on, she gave him sketchbooks and encouraged drawing excursions. Young Sargent worked with care on his drawings, and he enthusiastically copied images from The Illustrated London News of ships and made detailed sketches of landscapes. FitzWilliam had hoped that his son's interest in ships and the sea might lead him toward a naval career.

At thirteen, his mother reported that John "sketches quite nicely, & has a remarkably quick and correct eye. If we could afford to give him really good lessons, he would soon be quite a little artist." At age thirteen, he received some watercolor lessons from Carl Welsch, a German landscape painter. Though his education was far from complete, Sargent grew up to be a highly literate and cosmopolitan young man, accomplished in art, music, and literature. He was fluent in French, Italian, and German. At seventeen, Sargent was described as "willful, curious, determined and strong" (after his mother) yet shy, generous, and modest (after his father). He was well-acquainted with many of the great masters from first hand observation, as he wrote in 1874, "I have learned in Venice to admire Tintoretto immensely and to consider him perhaps second only to Michelangelo and Titian.

The Bauhaus

From Wikipedia: The Staatliches Bauhaus, commonly known simply as Bauhaus, was a school in Germany that combined crafts and the fine arts, and was famous for the approach to design that it publicized and taught. It operated from 1919 to 1933. At that time the German term About this sound Bauhaus, literally "house of construction" stood for "School of Building". The Bauhaus school was founded by Walter Gropius in Weimar. In spite of its name, and the fact that its founder was an architect, the Bauhaus did not have an architecture department during the first years of its existence. Nonetheless it was founded with the idea of creating a 'total' work of art in which all arts, including architecture would eventually be brought together. The Bauhaus style became one of the most influential currents in Modernist architecture and modern design. The Bauhaus had a profound influence upon subsequent developments in art, architecture, graphic design, interior design, industrial design, and typography. The school existed in three German cities (Weimar from 1919 to 1925, Dessau from 1925 to 1932 and Berlin from 1932 to 1933), under three different architect-directors: Walter Gropius from 1919 to 1928, Hannes Meyer from 1928 to 1930 and Ludwig Mies van der Rohe from 1930 until 1933, when the school was closed by its own leadership under pressure from the Nazi regime. The changes of venue and leadership resulted in a constant shifting of focus, technique, instructors, and politics. For instance: the pottery shop was discontinued when the school moved from Weimar to Dessau, even though it had been an important revenue source; when Mies van der Rohe took over the school in 1930, he transformed it into a private school, and would not allow any supporters of Hannes Meyer to attend it. Bauhaus and German modernism Germany's defeat in World War I, the fall of the German monarchy and the abolition of censorship under the new, liberal Weimar Republic allowed an upsurge of radical experimentation in all the arts, previously suppressed by the old regime. Many Germans of left-wing views were influenced by the cultural experimentation that followed the Russian Revolution, such as constructivism. Such influences can be overstated: Gropius himself did not share these radical views, and said that Bauhaus was entirely apolitical. Just as important was the influence of the 19th century English designer William Morris, who had argued that art should meet the needs of society and that there should be no distinction between form and function. Thus the Bauhaus style, also known as the International Style, was marked by the absence of ornamentation and by harmony between the function of an object or a building and its design. However, the most important influence on Bauhaus was modernism, a cultural movement whose origins lay as far back as the 1880s, and which had already made its presence felt in Germany before the World War, despite the prevailing conservatism. The design innovations commonly associated with Gropius and the Bauhaus—the radically simplified forms, the rationality and functionality, and the idea that mass-production was reconcilable with the individual artistic spirit—were already partly developed in Germany before the Bauhaus was founded. The German national designers' organization Deutscher Werkbund was formed in 1907 by Hermann Muthesius to harness the new potentials of mass production, with a mind towards preserving Germany's economic competitiveness with England. In its first seven years, the Werkbund came to be regarded as the authoritative body on questions of design in Germany, and was copied in other countries. Many fundamental questions of craftsmanship versus mass production, the relationship of usefulness and beauty, the practical purpose of formal beauty in a commonplace object, and whether or not a single proper form could exist, were argued out among its 1,870 members (by 1914). The entire movement of German architectural modernism was known as Neues Bauen. Beginning in June 1907, Peter Behrens' pioneering industrial design work for the German electrical company AEG successfully integrated art and mass production on a large scale. He designed consumer products, standardized parts, created clean-lined designs for the company's graphics, developed a consistent corporate identity, built the modernist landmark AEG Turbine Factory, and made full use of newly developed materials such as poured concrete and exposed steel. Behrens was a founding member of the Werkbund, and both Walter Gropius and Adolf Meier worked for him in this period. The Bauhaus was founded at a time when the German zeitgeist ("spirit of the times") had turned from emotional Expressionism to the matter-of-fact New Objectivity. An entire group of working architects, including Erich Mendelsohn, Bruno Taut and Hans Poelzig, turned away from fanciful experimentation, and turned toward rational, functional, sometimes standardized building. Beyond the Bauhaus, many other significant German-speaking architects in the 1920s responded to the same aesthetic issues and material possibilities as the school. They also responded to the promise of a "minimal dwelling" written into the new Weimar Constitution. Ernst May, Bruno Taut, and Martin Wagner, among others, built large housing blocks in Frankfurt and Berlin. The acceptance of modernist design into everyday life was the subject of publicity campaigns, well-attended public exhibitions like the Weissenhof Estate, films, and sometimes fierce public debate. Bauhaus and Vkhutemas Vkhutemas, the Russian state art and technical school founded in 1920 in Moscow, has been compared to Bauhaus. Founded a year after the Bauhaus school, Vkhutemas has close parallels to the German Bauhaus in its intent, organization and scope. The two schools were the first to train artist-designers in a modern manner. Both schools were state-sponsored initiatives to merge the craft tradition with modern technology, with a Basic Course in aesthetic principles, courses in color theory, industrial design, and architecture.Vkhutemas was a larger school than the Bauhaus, but it was less publicised outside the Soviet Union and consequently, is less familiar to the West. With the internationalism of modern architecture and design, there were many exchanges between the Vkhutemas and the Bauhaus The second Bauhaus director Hannes Meyer attempted to organise an exchange between the two schools, while Hinnerk Scheper of the Bauhaus collaborated with various Vkhutein members on the use of colour in architecture. In addition, El Lissitzky's book Russia: an Architecture for World Revolution published in German in 1930 featured several illustrations of Vkhutemas/Vkhutein projects there. History of the Bauhaus Weimar The school was founded by Walter Gropius in Weimar in 1919 as a merger of the Grand Ducal School of Arts and Crafts and the Weimar Academy of Fine Art. Its roots lay in the arts and crafts school founded by the Grand Duke of Saxe-Weimar-Eisenach in 1906 and directed by Belgian Art Nouveau architect Henry van de Velde. When van de Velde was forced to resign in 1915 because he was Belgian, he suggested Gropius, Hermann Obrist and August Endell as possible successors. In 1919, after delays caused by the destruction of World War I and a lengthy debate over who should head the institution and the socio-economic meanings of a reconciliation of the fine arts and the applied arts (an issue which remained a defining one throughout the school's existence), Gropius was made the director of a new institution integrating the two called the Bauhaus. In the pamphlet for an April 1919 exhibition entitled "Exhibition of Unknown Architects", Gropius proclaimed his goal as being "to create a new guild of craftsmen, without the class distinctions which raise an arrogant barrier between craftsman and artist." Gropius' neologism Bauhaus references both building and the Bauhütte, a premodern guild of stonemasons.[10] The early intention was for the Bauhaus to be a combined architecture school, crafts school, and academy of the arts. In 1919 Swiss painter Johannes Itten, German-American painter Lyonel Feininger, and German sculptor Gerhard Marcks, along with Gropius, comprised the faculty of the Bauhaus. By the following year their ranks had grown to include German painter, sculptor and designer Oskar Schlemmer who headed the theater workshop, and Swiss painter Paul Klee, joined in 1922 by Russian painter Wassily Kandinsky. A tumultuous year at the Bauhaus, 1922 also saw the move of Dutch painter Theo van Doesburg to Weimar to promote De Stijl ("The Style"), and a visit to the Bauhaus by Russian Constructivist artist and architect El Lissitzky. From 1919 to 1922 the school was shaped by the pedagogical and aesthetic ideas of Johannes Itten, who taught the Vorkurs or 'preliminary course' that was the introduction to the ideas of the Bauhaus. Itten was heavily influenced in his teaching by the ideas of Franz Cižek and Friedrich Wilhelm August Fröbel. He was also influenced in respect to aesthetics by the work of the Blaue Reiter group in Munich as well as the work of Austrian Expressionist Oskar Kokoschka. The influence of German Expressionism favoured by Itten was analogous in some ways to the fine arts side of the ongoing debate. This influence culminated with the addition of Der Blaue Reiter founding member Wassily Kandinsky to the faculty and ended when Itten resigned in late 1922. Itten was replaced by the Hungarian designer László Moholy-Nagy, who rewrote the Vorkurs with a leaning towards the New Objectivity favored by Gropius, which was analogous in some ways to the applied arts side of the debate. Although this shift was an important one, it did not represent a radical break from the past so much as a small step in a broader, more gradual socio-economic movement that had been going on at least since 1907 when van de Velde had argued for a craft basis for design while Hermann Muthesius had begun implementing industrial prototypes. Gropius was not necessarily against Expressionism, and in fact himself in the same 1919 pamphlet proclaiming this "new guild of craftsmen, without the class snobbery," described "painting and sculpture rising to heaven out of the hands of a million craftsmen, the crystal symbol of the new faith of the future." By 1923 however, Gropius was no longer evoking images of soaring Romanesque cathedrals and the craft-driven aesthetic of the "Völkisch movement", instead declaring "we want an architecture adapted to our world of machines, radios and fast cars." Gropius argued that a new period of history had begun with the end of the war. He wanted to create a new architectural style to reflect this new era. His style in architecture and consumer goods was to be functional, cheap and consistent with mass production. To these ends, Gropius wanted to reunite art and craft to arrive at high-end functional products with artistic pretensions. The Bauhaus issued a magazine called Bauhaus and a series of books called "Bauhausbücher". Since the Weimar Republic lacked the quantity of raw materials available to the United States and Great Britain, it had to rely on the proficiency of a skilled labor force and an ability to export innovative and high quality goods. Therefore designers were needed and so was a new type of art education. The school's philosophy stated that the artist should be trained to work with the industry. Weimar was in the German state of Thuringia, and the Bauhaus school received state support from the Social Democrat-controlled Thuringian state government. From 1923 the school in Weimar came under political pressure from right-wing circles, until on 26 December 1924 it issued a press release accusing the government and setting the closure of the school for the end of March 1925. In February 1924, the Social Democrats lost control of the state parliament to the Nationalists. The Ministry of Education placed the staff on six-month contracts and cut the school's funding in half. They had already been looking for alternative sources of funding. After the Bauhaus moved to Dessau, a school of industrial design with teachers and staff less antagonistic to the conservative political regime remained in Weimar. This school was eventually known as the Technical University of Architecture and Civil Engineering, and in 1996 changed its name to Bauhaus-University Weimar. The Bauhaus Dessau Gropius's design for the Dessau facilities was a return to the futuristic Gropius of 1914 that had more in common with the International style lines of the Fagus Factory than the stripped down Neo-classical of the Werkbund pavilion or the Völkisch Sommerfeld House. The Dessau years saw a remarkable change in direction for the school. According to Elaine Hoffman, Gropius had approached the Dutch architect Mart Stam to run the newly-founded architecture program, and when Stam declined the position, Gropius turned to Stam's friend and colleague in the ABC group, Hannes Meyer. Meyer became director when Gropius resigned in February 1928, and brought the Bauhaus its two most significant building commissions, both of which still exist: five apartment buildings in the city of Dessau, and the headquarters of the Federal School of the German Trade Unions (ADGB) in Bernau. Meyer favored measurements and calculations in his presentations to clients, along with the use of off-the-shelf architectural components to reduce costs, and this approach proved attractive to potential clients. The school turned its first profit under his leadership in 1929. But Meyer also generated a great deal of conflict. As a radical functionalist, he had no patience with the aesthetic program, and forced the resignations of Herbert Bayer, Marcel Breuer, and other long-time instructors. As a vocal Communist, he encouraged the formation of a communist student organization. In the increasingly dangerous political atmosphere, this became a threat to the existence of the Dessau school. Gropius fired him in the summer of 1930. Berlin Although neither the Nazi Party nor Hitler himself had a cohesive architectural policy before they came to power in 1933, Nazi writers like Wilhelm Frick and Alfred Rosenberg had already labeled the Bauhaus "un-German" and criticized its modernist styles, deliberately generating public controversy over issues like flat roofs. Increasingly through the early 1930s, they characterized the Bauhaus as a front for communists and social liberals. Indeed, a number of communist students loyal to Meyer moved to the Soviet Union when he was fired in 1930. Even before the Nazis came to power, political pressure on Bauhaus had increased. The Nazi movement, from nearly the start, denounced the Bauhaus for its "degenerate art", and the Nazi regime was determined to crack down on what it saw as the foreign, probably Jewish influences of "cosmopolitan modernism." Despite Gropius's protestations that as a war veteran and a patriot his work had no subversive political intent, the Berlin Bauhaus was pressured to close in April 1933. Emigrants did succeed, however, in spreading the concepts of the Bauhaus to other countries, including the “New Bauhaus” of Chicago: Mies van der Rohe decided to emigrate to the United States for the directorship of the School of Architecture at the Armour Institute (now IIT) in Chicago and to seek building commissions.[a] Curiously, however, some Bauhaus influences lived on in Nazi Germany. When Hitler's chief engineer, Fritz Todt, began opening the new autobahn (highways) in 1935, many of the bridges and service stations were "bold examples of modernism" – among those submitting designs was Mies van der Rohe. The paradox of the early Bauhaus was that, although its manifesto proclaimed that the ultimate aim of all creative activity was building, the school did not offer classes in architecture until 1927. During the years under Gropius (1919–1927), he and his partner Adolf Meyer observed no real distinction between the output of his architectural office and the school. So the built output of Bauhaus architecture in these years is the output of Gropius: the Sommerfeld house in Berlin, the Otte house in Berlin, the Auerbach house in Jena, and the competition design for the Chicago Tribune Tower, which brought the school much attention. The definitive 1926 Bauhaus building in Dessau is also attributed to Gropius. Apart from contributions to the 1923 Haus am Horn, student architectural work amounted to un-built projects, interior finishes, and craft work like cabinets, chairs and pottery. In the next two years under Meyer, the architectural focus shifted away from aesthetics and towards functionality. There were major commissions: one from the city of Dessau for five tightly designed "Laubenganghäuser" (apartment buildings with balcony access), which are still in use today, and another for the headquarters of the Federal School of the German Trade Unions (ADGB) in Bernau bei Berlin. Meyer's approach was to research users' needs and scientifically develop the design solution. Mies van der Rohe repudiated Meyer's politics, his supporters, and his architectural approach. As opposed to Gropius's "study of essentials", and Meyer's research into user requirements, Mies advocated a "spatial implementation of intellectual decisions", which effectively meant an adoption of his own aesthetics. Neither van der Rohe nor his Bauhaus students saw any projects built during the 1930s. The popular conception of the Bauhaus as the source of extensive Weimar-era working housing is not accurate. Two projects, the apartment building project in Dessau and the Törten row housing also in Dessau, fall in that category, but developing worker housing was not the first priority of Gropius nor Mies. It was the Bauhaus contemporaries Bruno Taut, Hans Poelzig and particularly Ernst May, as the city architects of Berlin, Dresden and Frankfurt respectively, who are rightfully credited with the thousands of socially progressive housing units built in Weimar Germany. In Taut's case, the housing he built in south-west Berlin during the 1920s, is still occupied, and can be reached by going easily from the U-Bahn stop Onkel Toms Hütte. Impact The Bauhaus had a major impact on art and architecture trends in Western Europe, the United States, Canada and Israel (particularly in the White City of Tel Aviv) in the decades following its demise, as many of the artists involved fled, or were exiled, by the Nazi regime. Tel Aviv, in fact, in 2004 was named to the list of world heritage sites by the UN due to its abundance of Bauhaus architecture; it had some 4,000 Bauhaus buildings erected from 1933 on. Walter Gropius, Marcel Breuer, and László Moholy-Nagy re-assembled in Britain during the mid 1930s to live and work in the Isokon project before the war caught up with them. Both Gropius and Breuer went to teach at the Harvard Graduate School of Design and worked together before their professional split. Their collaboration produced The Aluminum City Terrace in New Kensington, Pennsylvania and the Alan I W Frank House in Pittsburgh, among other projects. The Harvard School was enormously influential in America in the late 1920s and early 1930s, producing such students as Philip Johnson, I.M. Pei, Lawrence Halprin and Paul Rudolph, among many others. In the late 1930s, Mies van der Rohe re-settled in Chicago, enjoyed the sponsorship of the influential Philip Johnson, and became one of the pre-eminent architects in the world. Moholy-Nagy also went to Chicago and founded the New Bauhaus school under the sponsorship of industrialist and philanthropist Walter Paepcke. This school became the Institute of Design, part of the Illinois Institute of Technology. Printmaker and painter Werner Drewes was also largely responsible for bringing the Bauhaus aesthetic to America and taught at both Columbia University and Washington University in St. Louis. Herbert Bayer, sponsored by Paepcke, moved to Aspen, Colorado in support of Paepcke's Aspen projects at the Aspen Institute. In 1953, Max Bill, together with Inge Aicher-Scholl and Otl Aicher, founded the Ulm School of Design (German: Hochschule für Gestaltung – HfG Ulm) in Ulm, Germany, a design school in the tradition of the Bauhaus. The school is notable for its inclusion of semiotics as a field of study. The school closed in 1968, but the ′Ulm Model′ concept continues to influence international design education. One of the main objectives of the Bauhaus was to unify art, craft, and technology. The machine was considered a positive element, and therefore industrial and product design were important components. Vorkurs ("initial" or "preliminary course") was taught; this is the modern day "Basic Design" course that has become one of the key foundational courses offered in architectural and design schools across the globe. There was no teaching of history in the school because everything was supposed to be designed and created according to first principles rather than by following precedent. One of the most important contributions of the Bauhaus is in the field of modern furniture design. The ubiquitous Cantilever chair and the Wassily Chair designed by Marcel Breuer are two examples. (Breuer eventually lost a legal battle in Germany with Dutch architect/designer Mart Stam over the rights to the cantilever chair patent. Although Stam had worked on the design of the Bauhaus's 1923 exhibit in Weimar, and guest-lectured at the Bauhaus later in the 1920s, he was not formally associated with the school, and he and Breuer had worked independently on the cantilever concept, thus leading to the patent dispute.) The single most profitable tangible product of the Bauhaus was its wallpaper. The physical plant at Dessau survived World War II and was operated as a design school with some architectural facilities by the German Democratic Republic. This included live stage productions in the Bauhaus theater under the name of Bauhausbühne ("Bauhaus Stage"). After German reunification, a reorganized school continued in the same building, with no essential continuity with the Bauhaus under Gropius in the early 1920s. In 1979 Bauhaus-Dessau College started to organize postgraduate programs with participants from all over the world. This effort has been supported by the Bauhaus-Dessau Foundation which was founded in 1974 as a public institution. Bauhaus artists Bauhaus was not a formal group, but rather a school. Its three architect-directors (Walter Gropius, Hannes Meyer, and Ludwig Mies van der Rohe) are most closely associated with Bauhaus. Furthermore a large number of outstanding artists of their time were lecturers at Bauhaus: * Anni Albers * Josef Albers * Herbert Bayer * Max Bill * Marianne Brandt * Marcel Breuer * Avgust Černigoj * Christian Dell * Werner Drewes * Lyonel Feininger * Naum Gabo * Ludwig Hilberseimer * Ludwig Hirschfeld Mack * Johannes Itten * Wassily Kandinsky * Paul Klee * Otto Lindig * Gerhard Marcks * László Moholy-Nagy * Piet Mondrian * Oskar Schlemmer * Lothar Schreyer * Joost Schmidt * Naum Slutzky * Gunta Stölzl

Art: Op Art

From Wikipedia

Op art, also known as optical art, is a style of visual art that makes use of optical illusions.

"Optical art is a method of painting concerning the interaction between illusion and picture plane, between understanding and seeing." Op art works are abstract, with many of the better known pieces made in only black and white. When the viewer looks at them, the impression is given of movement, hidden images, flashing and vibration, patterns, or alternatively, of swelling or warping.

Historical context
Op art is derived from the constructivist practices of the Bauhaus. This German school, founded by Walter Gropius, stressed the relationship of form and function within a framework of analysis and rationality. Students were taught to focus on the overall design, or entire composition, in order to present unified works. When the Bauhaus was forced to close in 1933, many of its instructors fled to the United States where the movement took root in Chicago and eventually at the Black Mountain College in Asheville, North Carolina, where Anni and Josef Albers would come to teach.

Origin of "op"
The term first appeared in print in Time magazine in October 1964 in response to Julian Stanczak's show Optical Paintings at the Martha Jackson gallery, though works which might now be described as "op art" had been produced for several years previously. For instance, Victor Vasarely's painting, Zebras (1938), is made up entirely of curvilinear black and white stripes that are not contained by contour lines. Consequently, the stripes appear to both meld into and burst forth from the surrounding background of the composition. Also the early black and white Dazzle panels of John McHale installed at the This Is Tomorrow exhibit in 1956 and his Pandora series at the Institute of Contemporary Arts in 1962 demonstrate proto-op tendencies.

In the 1960s Arnold Schmidt (Arnold Alfred Schmidt) had several solo exhibitions of his large, black and white shaped optical paintings exhibited at the Terrain Gallery in New York. The term "Op" irritated many of the artists labeled under it, specifically including Albers and Stanczak. They had discussed upon the birth of the term a better label, namely perceptual art.

The Responsive Eye
In 1965, between February 23rd and April 25th an exhibition called The Responsive Eye, created by William C. Seitz was held at the Museum of Modern Art in New York City. The works shown were wide ranging, encompassing the minimalism of Frank Stella and Ellsworth Kelly, the smooth plasticity of Alexander Liberman, the collaborative efforts of the Anonima group, alongside the well-known Victor Vasarely, Richard Anuszkiewicz, and Bridget Riley. The exhibition focused on the perceptual aspects of art, which result both from the illusion of movement and the interaction of color relationships. The exhibition was enormously popular with the general public, though less so with the critics.[7] Critics dismissed op art as portraying nothing more than trompe l'oeil, or tricks that fool the eye. Regardless, op art's popularity with the public increased, and op art images were used in a number of commercial contexts. Bridget Riley tried to sue an American company, without success, for using one of her paintings as the basis of a fabric design.

The Op Art movement got a new lease of life in the first decade of the twenty-first century as new forms started once again emerging. In 2005, Indian artist, Devajyoti Ray started a new genre of art called Pseudorealism. Though the concept and the name of the movement was brought from the film-world, much of Pseudorealism depends on the intuitive use of colours and understanding the relationships between them.


How op art works
Black-and-white and the figure-ground relationship


Op art is a perceptual experience related to how vision functions. It is a dynamic visual art, stemming from a discordant figure-ground relationship that causes the two planes to be in a tense and contradictory juxtaposition. Op art is created in two primary ways. The first, and best known method, is the creation of effects through the use of pattern and line. Often these paintings are black-and-white, or otherwise grisaille, as in Bridget Riley's famous painting, Current (1964), on the cover of The Responsive Eye catalogue; here, black and white wavy lines are placed close to one another on the canvas surface, creating such a volatile figure-ground relationship that one's eyes begin to hurt.

Getulio Alviani chose aluminium surfaces, treated in order to create patterns of light which change as the watcher moves (vibrating texture surfaces). Another reaction that occurs is that the lines create after- images of certain colors due to how the retina receives and processes light. As Goethe demonstrates in his treatise Theory of Colours, at the edge where light and dark meet, color arises because lightness and darkness are the two central properties in the creation of color.

Color
Beginning in 1966 Bridget Riley began to produce color-based op art, however, other artists, such as Julian Stanczak and Richard Anuszkiewicz, were always interested in making color the primary focus of their work. Josef Albers taught these two primary practitioners of the "Color Function" school at Yale in the 1950s. Often, colorist work is dominated by the same concerns of figure-ground movement, but they have the added element of contrasting colors which have different effects on the eye. For instance, in Anuszkiewicz's "temple" paintings, the juxtaposition of two highly contrasting colors provokes a sense of depth in illusionistic three-dimensional space so that it appears as if the architectural shape is invading the viewer's space.

Stanczak's compositions tend to be the most complex of all of the color function practitioners. Taking his cue from Albers and his influential book Interaction of Color, Stanczak deeply investigates how color relationships work. "Stanczak created various spatial experiences with color and geometry; the latter is far easier to discuss. Color has no simple systematized equivalent. Indeed, there may be no way to describe it that is both meaningful and accurate. Descriptions of it (the color wheel or color solids, for example) are all necessary distortions. While color derives from the electromagnetic scale that corresponds to the magnitudes of energy expressed by musical pitch, in fact, the neurological occidentals by which we experience color make it seem multidimensional, while musical pitch (not timbre, volume, or duration) is experienced as a linear relationship...Stanczak's 'gift is for layering. He arranges transparent patterns upon patterns so that you see through them as gauziest screens, each one seeming to fold as if it moves.'"

Color interaction
There are three major classes of the interaction of color: simultaneous contrast, successive contrast, and reverse contrast (or assimilation).

(1) Simultaneous contrast may take place when one area of color is surrounded by another area of a different color. In general, contrast enhances the difference in brightness and/or color between the interacting areas...Such contrast effects are mutual, but if the surround area is larger and more intense than the area it encloses, then the contrast is correspondingly out of balance, any may appear to be exerted in one direction only.

(ii) In successive contrast, first one color is viewed and then another. This may be achieved either by fixing the eye steadily on one color and then quickly replacing that color with another, or by shifting fixation from one color to another.

(iii) In reverse contrast (sometimes called the assimilation of color or the spreading effect) the lightness of white or the darkness of black may seem to spread into neighboring regions. Similarly, colors may appear to spread into or become assimilated into neighboring areas. All such effects tend to make neighboring areas appear more alike, rather than to enhance their differences as in the more familiar simultaneous contrast, hence the term reverse contrast (Jameson and Hurvich, 1974). Note that in the interaction of color the constituent colors retain much of the own identity even though they may be altered somewhat by contrast.

[edit] Photographic op art

Although being relatively mainstream, photographers have been slow to produce op art. In painting, Victor Vasarely and Bridget Riley were producing large amounts of art and the same can be said for many digital artists, such as Kitaoka. One of the primary reasons for the lack of photographers doing op art, is the difficulty in finding effective subject matter. Laszlo Moholy-Nagy, however, produced photographic op art and taught the subject in the Bauhaus. One of his lessons consisted of making his students produce holes in cards and then photographing them.

Titian


Titian self-portrait, c.1567; Museo del Prado, Madrid

Tiziano Vecelli or Tiziano Vecellio (c. 1488/1490 – 27 August 1576 known in English as Titian was an Italian painter, the most important member of the 16th-century Venetian school. He was born in Pieve di Cadore, near Belluno (in Veneto), in the Republic of Venice. During his lifetime he was often called da Cadore, taken from the place of his birth.

Recognized by his contemporaries as "The Sun Amidst Small Stars" (recalling the famous final line of Dante's Paradiso), Titian was one of the most versatile of Italian painters, equally adept with portraits, landscape backgrounds, and mythological and religious subjects. His painting methods, particularly in the application and use of color, would exercise a profound influence not only on painters of the Italian Renaissance, but on future generations of Western art.

During the course of his long life, Titian's artistic manner changed drastically but he retained a lifelong interest in color. Although his mature works may not contain the vivid, luminous tints of his early pieces, their loose brushwork and subtlety of polychromatic modulations are without precedent in the history of Western art.

Biography
Early years

The exact date of Titian's birth is uncertain; when he was an old man he claimed in a letter to Philip II to have been born in 1474, but this seems most unlikely. Other writers contemporary to his old age give figures which would equate to birthdates between 1473 to after 1482, but most modern scholars believe a date nearer 1490 is more likely; the Metropolitan Museum of Art's timeline supports c.1488, as does the Getty Research Institute.

He was the eldest son of Gregorio Vecelli and his wife Lucia. His father was superintendent of the castle of Pieve di Cadore and managed local mines for their owners. Gregorio was also a distinguished councilor and soldier. Many relatives, including Titian's grandfather, were notaries, and the family of four were well-established in the area, which was ruled by Venice.

At the age of about ten to twelve he and his brother Francesco (who perhaps followed later) were sent to an uncle in Venice to find an apprenticeship with a painter. The minor painter Sebastian Zuccato, whose sons became well-known mosaicists, and who may have been a family friend, arranged for the brothers to enter the studio of the elderly Gentile Bellini, from which they later transferred to that of his brother Giovanni Bellini.

At that time the Bellinis, especially Giovanni, were the leading artists in the city. There Titian found a group of young men about his own age, among them Giovanni Palma da Serinalta, Lorenzo Lotto, Sebastiano Luciani, and Giorgio da Castelfranco, nicknamed Giorgione. Francesco Vecellio, his older brother, later became a painter of some note in Venice.

A fresco of Hercules on the Morosini Palace is said to have been one of Titian's earliest works; others were the Bellini-esque so-called Gypsy Madonna in Vienna, and the Visitation of Mary and Elizabeth (from the convent of S. Andrea), now in the Accademia, Venice.

Titian joined Giorgione as an assistant, but many contemporary critics already found his work more impressive, for example in the exterior frescoes (now almost totally destroyed) that they did for the Fondaco dei Tedeschi (state-warehouse for the German merchants), and their relationship evidently had a significant element of rivalry. Distinguishing between their work at this period remains a subject of scholarly controversy, and there has been a substantial movement of attributions from Giorgione to Titian in the 20th century, with little traffic the other way.

One of the earliest known works of Titian, Christ Carrying the Cross in the Scuola Grande di San Rocco, depicting the Ecce Homo scene, was long regarded as the work of Giorgione.

The two young masters were likewise recognized as the two leaders of their new school of arte moderna, which is characterized by paintings made more flexible, freed from symmetry and the remnants of hieratic conventions still to be found in the works of Giovanni Bellini.

In 1507–1508 Giorgione was commissioned by the state to create frescoes on the re-erected Fondaco dei Tedeschi. Titian and Morto da Feltre worked along with him, and some fragments of paintings remain, probably by Giorgione. Some of their work is known, in part, through the engravings of Fontana. After Giorgione's early death in 1510, Titian continued to paint Giorgionesque subjects for some time, though his style developed its own features, including bold and expressive brushwork.

From Padua in 1512, Titian returned to Venice; and in 1513 he obtained a broker's patent, termed La Sanseria or Senseria (a privilege much coveted by rising or risen artists), in the Fondaco dei Tedeschi and became superintendent of the government works, being especially charged to complete the paintings left unfinished by Giovanni Bellini in the hall of the great council in the ducal palace. He set up an atelier on the Grand Canal at S. Samuele, the precise site being now unknown. It was not until 1516, after the death of Giovanni Bellini, that he came into actual enjoyment of his patent. At the same time he entered an exclusive arrangement for painting. The patent yielded him a good annuity of 20 crowns and exempted him from certain taxes—he being bound in return to paint likenesses of the successive Doges of his time at the fixed price of eight crowns each. The actual number he painted was five.

Growth
It took Titian two years (1516–1518) to complete his Assunta, whose dynamic three-tier composition and color scheme established him as the preeminent painter north of Rome.

During this period (1516–1530), which may be called the period of his mastery and maturity, the artist moved on from his early Giorgionesque style, undertook larger and more complex subjects and for the first time attempted a monumental style. Giorgione died in 1510 and Giovanni Bellini in 1516, leaving Titian unrivaled in the Venetian School. For sixty years he was to be the undisputed master of Venetian painting. In 1516 he completed for the high altar of the church of the Frari, his famous masterpiece, the Assumption of the Virgin, still in situ. This extraordinary piece of colorism, executed on a grand scale rarely before seen in Italy, created a sensation. The Signoria took note, and observed that Titian was neglecting his work in the hall of the great council, but in 1516 he succeeded his master Giovanni Bellini in receiving a pension from the Senate.

The pictorial structure of the Assumption—that of uniting in the same composition two or three scenes superimposed on different levels, earth and heaven, the temporal and the infinite — was continued in a series of works such as the retable of San Domenico at Ancona (1520), the retable of Brescia (1522), and the retable of San Niccolò (1523), in the Vatican Museum), each time attaining to a higher and more perfect conception, finally reaching a classic formula in the Pesaro Madonna, (better known as the Madonna di Ca' Pesaro) (c. 1519–1526), also for the Frari church. This perhaps is his most studied work, whose patiently developed plan is set forth with supreme display of order and freedom, originality and style. Here Titian gave a new conception of the traditional groups of donors and holy persons moving in aerial space, the plans and different degrees set in an architectural framework.

Titian was now at the height of his fame, and towards 1521, following the production of a figure of St. Sebastian for the papal legate in Brescia (a work of which there are numerous replicas), purchasers pressed for his work.

To this period belongs a more extraordinary work, The Death of St. Peter Martyr (1530), formerly in the Dominican Church of San Zanipolo, and destroyed by an Austrian shell in 1867. Only copies and engravings of this proto-Baroque picture remain; it combined extreme violence and a landscape, mostly consisting of a great tree, that pressed into the scene and seems to accentuate the drama in a way that looks forward to the Baroque.

The artist simultaneously continued his series of small Madonnas which he treated amid beautiful landscapes in the manner of genre pictures or poetic pastorals, the Virgin with the Rabbit in the Louvre being the finished type of these pictures. Another work of the same period, also in the Louvre, is the Entombment. This was also the period of the three large and famous mythological scenes for the camerino of Alfonso d'Este in Ferrara, The Andrians and the Worship of Venus in the Prado, and the Bacchus and Ariadne (1520–23) in London,"...perhaps the most brilliant productions of the neo-pagan culture or "Alexandrianism" of the Renaissance, many times imitated but never surpassed even by Rubens himself."

Finally this was the period when the artist composed the half-length figures and busts of young women, probably courtesans, such as Flora of the Uffizi, or Woman at the Mirror in the Louvre (the scientific images of this painting are available, with explanations, on the website of the French Center for Research and Restoration of the Museums of France).

Titian's wife, Cecilia—a barber's daughter from his hometown village of Cadore—was a young woman who had been his housekeeper and mistress for some five years. Cecilia had already borne Titian two fine sons, Pomponio and Orazio, when in 1525 she fell seriously ill. Titian, wishing to legitimize the children, married her. The marriage was a happy one and Cecilia recovered and bore him two more children, both daughters. Only one of them, Lavinia, survived. Titian's favorite child was Orazio, who became his assistant.

In August 1530 his wife died giving birth to daughter Lavinia, and with his two boys plus infant girl he moved house, and convinced his sister Orsa to come from Cadore and take charge of the household. The mansion, difficult to find now, is in the Biri Grande, then a fashionable suburb, at the extreme end of Venice, on the sea, with beautiful gardens and a view towards Murano. In about 1526 he had became acquainted, and soon intimate, with Pietro Aretino, the influential and audacious figure who features so strangely in the chronicles of the time. Titian sent a portrait of him to Gonzaga, duke of Mantua.

Maturity
During the next period (1530–1550), Titian developed the style introduced by his dramatic Death of St. Peter Martyr. The Venetian government, dissatisfied with Titian's neglect of the work for the ducal palace, ordered him in 1538 to refund the money which he had received, and Pordenone, his rival of recent years, was installed in his place. However, at the end of a year Pordenone died, and Titian, who meanwhile applied himself diligently to painting in the hall the Battle of Cadore, was reinstated. This major battle scene was lost along with so many other major works by Venetian artists by the great fire which destroyed all the old pictures in the great chambers of the Doge's Palace in 1577.

It represented in life-size the moment at which the Venetian general, D'Alviano attacked the enemy with horses and men crashing down into a stream, and was the artist's most important attempt at a tumultuous and heroic scene of movement to rival Raphael's Battle of Constantine and the equally ill-fated Battle of Cascina of Michelangelo and The Battle of Anghiari of Leonardo (both unfinished). There remains only a poor, incomplete copy at the Uffizi, and a mediocre engraving by Fontana. The Speech of the Marquis del Vasto (Madrid, 1541) was also partly destroyed by fire. But this period of the master's work is still represented by the Presentation of the Blessed Virgin (Venice, 1539), one of his most popular canvasses, and by the Ecce Homo (Vienna, 1541). Despite its loss, the painting had a great influence on Bolognese art and Rubens, both in the handling of details and the general effect of horses, soldiers, lictors, powerful stirrings of crowds at the foot of a stairway, lit by torches with the flapping of banners against the sky.

Titian's unmatched handling of color is exemplified by his Danaë with Nursemaid, one of several mythological paintings, or "poesie" ("poems") as the painter called them, done for Philip II of Spain. Although Michelangelo adjudged this piece deficient from the point of view of drawing, Titian and his studio produced several versions for other patrons.

Less successful were the pendentives of the cupola at Santa Maria della Salute (Death of Abel, Sacrifice of Abraham, David and Goliath). These violent scenes viewed in perspective from below—like the famous pendentives of the Sistine Chapel Ceiling—were by their very nature in unfavorable situations. They were nevertheless much admired and imitated, Rubens among others applying this system to his forty ceilings (the sketches only remain) of the Jesuit church at Antwerp.

At this time also, during his visit to Rome, the artist began his series of reclining Venuses (The Venus of Urbino of the Uffizi, Venus and Love at the same museum, Venus and the Organ-Player, Madrid), in which is recognized the effect or the direct reflection of the impression produced on the master by contact with ancient sculpture. Giorgione had already dealt with the subject in his Dresden picture, finished by Titian, but here a purple drapery substituted for a landscape background changed, by its harmonious coloring, the whole meaning of the scene.

Titian had from the beginning of his career shown himself to be a masterful portrait-painter, in works like La Bella (Eleanora de Gonzaga, Duchess of Urbino, at the Pitti Palace). He painted the likenesses of princes, or Doges, cardinals or monks, and artists or writers. "...no other painter was so successful in extracting from each physiognomy so many traits at once characteristic and beautiful", according to The Catholic Encyclopedia. Among portrait-painters Titian is compared to Rembrandt and Velázquez, with the interior life of the former, and the clearness, certainty, and obviousness of the latter.

Titian's state portrait of Emperor Charles V (1548) at Mühlberg established a new genre, that of the grand equestrian portrait. The composition is steeped both in the Roman tradition of equestrian sculpture and in the medieval representations of an ideal Christian knight, but the weary figure and face have a subtlety few such representations attempt.

The last-named qualities are sufficiently manifested in the Portrait of Paul III of Naples, or the sketch of the same pope and his two nephews, the Portrait of Aretino of the Pitti Palace, the Eleanora of Portugal (Madrid), and the series of Emperor Charles V of the same museum, the Charles V with a Greyhound (1533), and especially the Equestrian Portrait of Charles V (1548), an equestrian picture which as a symphony of purples is perhaps the ne plus ultra of the art of painting. In 1532 after painting a portrait of the emperor Charles V in Bologna he was made a Count Palatine and knight of the Golden Spur. His children were also made nobles of the Empire, which for a painter was an exceptional honor.

The Rape of Europa (1562) is a bold diagonal composition which was admired and copied by Rubens. In contrast to the clarity of Titian's early works, it is almost baroque in its blurred lines, swirling colors, and vibrant brushstrokes.

As a matter of professional and worldly success his position from about this time is regarded as equal only to that of Raphael, Michelangelo, and at a later date Rubens. In 1540 he received a pension from D'Avalos, marquis del Vasto, and an annuity of 200 crowns (which was afterwards doubled) from Charles V from the treasury of Milan. Another source of profit, for he was always aware of money, was a contract obtained in 1542 for supplying grain to Cadore, where he visited almost every year and where he was both generous and influential.

Titian had a favorite villa on the neighboring Manza Hill (in front of the church of Castello Roganzuolo) from which (it may be inferred) he made his chief observations of landscape form and effect. The so-called Titian's mill, constantly discernible in his studies, is at Collontola, near Belluno.

He visited Rome in 1546, and obtained the freedom of the city—his immediate predecessor in that honor having been Michelangelo in 1537. He could at the same time have succeeded the painter Sebastiano del Piombo in his lucrative office as holder of the piombo or Papal seal, and he was prepared to take holy orders for the purpose; but the project lapsed through his being summoned away from Venice in 1547 to paint Charles V and others in Augsburg. He was there again in 1550, and executed the portrait of Philip II which was sent to England and proved useful in Philip's suit for the hand of Queen Mary.

Final years
The Death of Actaeon. In Titian's later works, the forms lose their solidity and melt into the lush texture of shady, shimmering colors and unsettling atmospheric effects. In addition to energetic brushwork, Titian was said to put paint on with his fingers toward the completion of a painting.

During the last twenty-six years of his life (1550–1576) the artist worked mainly for Philip II and as a portrait-painter. He became more self-critical, an insatiable perfectionist, keeping some pictures in his studio for ten years, never wearying of returning to them and retouching them, constantly adding new expressions at once more refined, concise, and subtle. He also finished off many copies of earlier works of his by his pupils, giving rise to many problems of attribution and priority among versions of his works, which were also very widely copied and faked outside his studio, during his lifetime and afterwards.

For Philip II he painted a series of large mythological paintings known as the "poesie", mostly from Ovid, which are regarded as among his greatest works. Thanks to the prudishness of Philip's successors, these were later mostly given as gifts and only two remain in the Prado. Titian was producing religious works for Philip at the same time. The "poesie" series began with Venus and Adonis, of which the original is in the Prado, but several versions exist, and Danaë, both sent to Philip in 1553.

Diana and Actaeon and Diana and Callisto, were despatched in 1559, then Perseus and Andromeda (Wallace Collection, now damaged) and the Rape of Europa (Boston, Isabella Stewart Gardner Museum), delivered in 1562. The Death of Actaeon was begun in 1559 but worked on for many years, and never completed or delivered.

Another painting that apparently remained in his studio at his death, and has been much less well known until recent decades, is the powerful, even "repellant", Flaying of Marsyas (Kroměříž, Czech Republic) Another violent masterpiece is the Tarquin and Lucretia (Cambridge, Fitzwilliam Museum).

For each of the problems which he successively undertook he furnished a new and more perfect formula. He never again equaled the emotion and tragedy of the The Crowning with Thorns (Louvre), in the expression of the mysterious and the divine he never equaled the poetry of the Pilgrims of Emmaus, while in superb and heroic brilliancy he never again executed anything more grand than The Doge Grimani adoring Faith (Venice, Doge's Palace), or the Trinity, of Madrid. On the other hand from the standpoint of flesh tints, his most moving pictures are those of his old age, such as the poesie and the Antiope of the Louvre. He even attempted problems of chiaroscuro in fantastic night effects (Martyrdom of St. Laurence, Church of the Jesuits, Venice; St. Jerome, Louvre; Crucifixion, Church of San Domenico, Ancona).

Titian had engaged his daughter Lavinia, the beautiful girl whom he loved deeply and painted various times, to Cornelio Sarcinelli of Serravalle. She had succeeded her aunt Orsa, then deceased, as the manager of the household, which, with the lordly income that Titian made by this time, placed her on a corresponding footing. The marriage took place in 1554. She died in childbirth in 1560.

Like numerous of his late works, Titian's last painting, the Pietà, is a dramatic scene of suffering in a nocturnal setting. It was apparently intended for his own tomb chapel.

He was at the Council of Trent towards 1555, of which there is a finished sketch in the Louvre. Titian's friend Aretino died suddenly in 1556, and another close intimate, the sculptor and architect Jacopo Sansovino, in 1570. In September 1565 Titian went to Cadore and designed the decorations for the church at Pieve, partly executed by his pupils. One of these is a Transfiguration, another an Annunciation (now in S. Salvatore, Venice), inscribed Titianus fecit, by way of protest (it is said) against the disparagement of some persons who caviled at the veteran's failing handicraft.

Around 1560 Titian painted the oil on canvas Sacra Conversazione: The Madonna and Child with Saints Luke and Catherine of Alexandria, a derivative on the motif of Madonna and Child. It is suggested that members of Titian's Venice workshop probably painted the curtain and Luke, because of the lower quality of those parts.

He continued to accept commissions to the end of his life. He had selected as the place for his burial the chapel of the Crucifix in the Santa Maria Gloriosa dei Frari, the church of the Franciscan Order; in return for a grave, he offered the Franciscans a picture of the Pietà, representing himself and his son Orazio before the Savior, another figure in the composition being a sibyl. This work he nearly finished, but some differences arose regarding it, and he then settled to be interred in his native Pieve.

Titian was (depending on his unknown birthdate—see above) probably in his late eighties when the plague raging in Venice took him on 27 August 1576. He was the only victim of the Venice plague to be given a church burial. He was interred in the Frari (Santa Maria Gloriosa dei Frari), as at first intended, and his Pietà was finished by Palma the Younger. He lies near his own famous painting, the Madonna di Ca' Pesaro. No memorial marked his grave, until much later the Austrian rulers of Venice commissioned Canova to provide the large monument.

Immediately after Titian's own death, his son and assistant Orazio died of the same epidemic. His sumptuous mansion was plundered during the plague by thieves.

Printmaking

Titian himself never attempted engraving, but he was very conscious of the importance of printmaking as a means of further expanding his reputation. In the period 1517–1520 he designed a number of woodcuts, including an enormous and impressive one of The Crossing of the Red Sea, and collaborated with Domenico Campagnola and others, who produced further prints based on his paintings and drawings. Much later he provided drawings based on his paintings to Cornelius Cort from the Netherlands who engraved them. Martino Rota followed Cort from about 1558 to 1568.

Family
The Allegory of Age Governed by Prudence (c. 1565–1570) is thought to depict Titian, his son Orazio, and a young cousin, Marco Vecellio.

Several other artists of the Vecelli family followed in the wake of Titian. Francesco Vecellio, his elder brother, was introduced to painting by Titian (it is said at the age of twelve, but chronology will hardly admit of this), and painted in the church of S. Vito in Cadore a picture of the titular saint armed. This was a noteworthy performance, of which Titian (the usual story) became jealous; so Francesco was diverted from painting to soldiering, and afterwards to mercantile life.

Marco Vecellio, called Marco di Tiziano, Titian's nephew, born in 1545, was constantly with the master in his old age, and learned his methods of work. He has left some able productions in the ducal palace, the Meeting of Charles V. and Clement VII. in 1529 ; in S. Giacomo di Rialto, an Annunciation ; in SS. Giovani e Paolo, Christ Fulminant. A son of Marco, named Tiziano (or Tizianello), painted early in the 17th century.

From a different branch of the family came Fabrizio di Ettore, a painter who died in 1580. His brother Cesare, who also left some pictures, is well known by his book of engraved costumes, Abiti antichi e moderni. Tommaso Vecelli, also a painter, died in 1620. There was another relative, Girolamo Dante, who, being a scholar and assistant of Titian, was called Girolamo di Tiziano. Various pictures of his were touched up by the master, and are difficult to distinguish from originals.

Few of the pupils and assistants of Titian became well known in their own right; for some being his assistant was probably a lifetime career. Paris Bordone and Bonifazio Veronese were his assistants during at some point in their careers. Giulio Clovio said Titian employed El Greco (or Dominikos Theotokopoulos) in his last years.

Present day
The Flaying of Marsyas, little known until recent decades, Gallery in Kroměříž - Czech Republic

Two of Titian's works in private hands have been up for sale. One of these works, Diana and Actaeon, was purchased by London's National Gallery and the National Galleries of Scotland on 2 February 2009 for ₤50 million ($71 million). The galleries had until 31 December 2008 to make the purchase before the work would be offered to private collectors, but the deadline was extended. The other painting, Diana and Callisto, will be up for sale for the same amount until 2012 before it is offered to private collectors.

The sale has created controversy with politicians who said "the money, some of which came from government funds, could have been spent more wisely during a deepening recession." The Scottish government offered ₤12.5 million and ₤10 million came from the National Heritage Memorial Fund. The rest of the money came from the National Galleries in London and from private donations.

In 2011, A Sacra Conversazione: The Madonna and Child with Saints Luke and Catherine of Alexandria, was put for an auction at Sotheby's, and it was sold on 28. January 2011 for $16.9 million.

On 11 February 2009, an argument about Titian's age at death arose between British Prime Minister Gordon Brown, and Leader of the Opposition David Cameron at Prime Minister's Questions, where Cameron was attempting to ridicule Brown's general factual accuracy. This debate spilt over onto Titian's entry on Wikipedia, when an editor from Conservative Party HQ altered Titian's dates to substantiate David Cameron's claim and then directed the BBC to the article for them to use as verification. Cameron later apologized and said the staff member had been "disciplined". The precise date of Titian's birth is uncertain (see above).

The reference was to Brown's comment on 30 January 2009 to the World Economic Forum in Davos:

This is the first financial crisis of the global age, and there is no clear map that has been set out from past experience to deal with it. I'm reminded of the story of Titian, who's the great painter who reached the age of 90, finished the last of his nearly 100 brilliant paintings, and he said at the end of it, "I'm finally beginning to learn how to paint", and that is where we are.

Rembrandt Van Rijn pt 1


self portrait

Rembrandt Harmenszoon van Rijn (15 July 1606 – 4 October 1669) was a Dutch painter and etcher. He is generally considered one of the greatest painters and printmakers in European art history and the most important in Dutch history. His contributions to art came in a period of great wealth and cultural achievement that historians call the Dutch Golden Age, when Dutch Golden Age painting, although in many ways antithetical to the Baroque style that dominated Europe, was extremely prolific and innovative.

Having achieved youthful success as a portrait painter, Rembrandt's later years were marked by personal tragedy and financial hardships. Yet his etchings and paintings were popular throughout his lifetime, his reputation as an artist remained high, and for twenty years he taught many important Dutch painters. Rembrandt's greatest creative triumphs are exemplified especially in his portraits of his contemporaries, self-portraits and illustrations of scenes from the Bible. His self-portraits form a unique and intimate biography, in which the artist surveyed himself without vanity and with the utmost sincerity.

In his paintings and prints he exhibited knowledge of classical iconography, which he molded to fit the requirements of his own experience; thus, the depiction of a biblical scene was informed by Rembrandt's knowledge of the specific text, his assimilation of classical composition, and his observations of Amsterdam's Jewish population. Because of his empathy for the human condition, he has been called "one of the great prophets of civilization."
