Art Terminology: Acanthus and Altarpiece

Acanthus
Architecture: A prickly plant of the Mediterranean region with large, deeply cleft and scalloped leaves which are freely imitated on the capitals of the Corinthian and Composite orders and often used, in varying degrees of abstraction, to ornament moldings, brackets, friezes and so on.

Altarpiece
Architecture: A painted or sculpted panel or shrine placed behind and above an altar, also called a "reredos" or "retable." 14th and 15th century altarpieces are often very complicated, consisting of several panels or separate groups of sculpture.

An altarpiece consisting of three panels is called a tryptych, when it has more than three panels it is called a "poylptych". Some altarpieces have a decorated base, or pedella, and have "shutters" or "wings" which can be opened to reveal a series of "transformations" or "stages" to reveal other paintings or sculptures. The shutters are usually painted in rather subdued colors on the outside - monochrome imitations of sculpture ("grisailles") being common in northern Europe - but when opened up for the feast days of the Church, they offer a brilliant and sumptuous display pf color.
