Definition: Acanthus (the Greek and Latin name for the plant, connected
with "ake," a sharp point), a genus of plants belonging to
the natural order Acanthaceae. The species are natives of
the southern parts of Europe and the warmer parts of Asia and
Africa. The best-known is Acanthus mollis (brank-ursine, or
bears' breech), a common species throughout the Mediterranean
region, having large, deeply cut, hairy, shining leaves. Another
species, Acanthus spinosus, is so called from its spiny
heaves. They are bold, handsome plants, with stately spikes,
2 to 3 ft. high, of flowers with spiny bracts. A. mollis, A.
latifolius and A. longifolius are broad-leaved species; A.
spinosus and A. spinosissimus have narrower, spiny toothed
leaves. In decoration, the acanthus was first reproduced in
metal, and subsequently carved in stone by the Greeks. It was
afterwards, with various changes, adopted in all succeeding
styles of architecture as a basis of ornamental decoration.
There are two types, that found in the Acanthus spinosus,
which was followed by the Greeks, and that in the Acanthus
mollis, which seems to have been preferred by the Romans.
