Corinthian Order:
- most ornate of the classic orders of architecture. It was also the latest, not arriving at full development until the middle of the 4th cent. B.C. The oldest known example, however, is found in the temple of Apollo at Bassae (c.420 B.C.). The Greeks made little use of the order; the chief example is the circular structure at Athens known as the choragic monument of Lysicrates ( 335 B.C.). The temple of Zeus at Athens (started in the 2d cent. B.C. and completed by Emperor Hadrian in the 2d cent. A.D.) was perhaps the most notable of the Corinthian temples.
