According to Pliny, Alcamenes was born at Athens. Other authorities call him a native of the island of Lemnos. He was a pupil, and according to some a rival, of Phidias. He flourished from 448 B.C. until the end of the fifth century. The sculpture of the western pediment of the temple of Zeus (Jupiter) at Olympia is attributed to Alcamenes by Pausanias. The crude character of the work and its early date (about 456 B.C.) make this attribution doubtful.
