Acanthus (ornament)

The acanthus (ἄκανθος) is one of the most common plant forms to make foliage ornament and decoration in the architectural tradition emanating from Greece and Rome. In architecture, an ornament may be carved into stone or wood to resemble leaves from the Mediterranean species of the Acanthus genus of plants, which have deeply cut leaves with some similarity to those of the thistle and poppy. Both Acanthus mollis and the still more deeply cut Acanthus spinosus have been claimed as the main model, and particular examples of the motif may be closer in form to one or the other species; the leaves of both are, in any case, rather variable in form. The motif is found in decoration in nearly every medium. The relationship between acanthus ornament and the acanthus plant has been the subject of a long-standing controversy. Alois Riegl argued in his Stilfragen that acanthus ornament originated as a sculptural version of the palmette, and only later began to resemble Acanthus spinosus. In ancient Roman and ancient Greek architecture acanthus ornament appears extensively in the capitals of the Corinthian and Composite orders, and applied to friezes, dentils and other decorated areas. The oldest known example of a Corinthian column is in the Temple of Apollo Epicurius at Bassae in Arcadia, c. 450–420 BC, but the order was used sparingly in Greece before the Roman period. The Romans elaborated the order with the ends of the leaves curled, and it was their favourite order for grand buildings, with their own invention of the Composite, which was first seen in the epoch of Augustus. Acanthus decoration continued in popularity in Byzantine, Romanesque, and Gothic architecture. It saw a major revival in the Renaissance, and still is used today. The Roman writer Vitruvius (c. 75 – c. 15 BC) related that the Corinthian order had been invented by Callimachus, a Greek architect and sculptor who was inspired by the sight of a votive basket that had been left on the grave of a young girl.
