DEINOCRATES, or, as his name is sometimes written, DINOCRARES or TYMOCHARES, a celebrated Macedonian architect, who flourished in the time of Alexander the Great. He furnished the designs for the second temple of Diana at Ephesus; drew plans, which he submitted to Alexander, for cutting Mount Athos into a statue of that hero; and, at the command of Ptolemy Philadelphus, prepared to build a temple at Alexandria in honour of that monarch's deceased wife Arsinoë, the roof of which was intended to be arched with load-stones, so that the iron statue of the late queen might seem to float in mid-air. The exact dates of Deinocrates's birth and death are unknown.
