Cnidus or Cnidos (both: nī´dəs), ancient Greek city of Caria, SW Asia Minor, on Cape Krio, in present SW Asian Turkey. It was partly on the peninsula and partly on an island that had been created by cutting through the peninsula. One of the cities of the Dorian Hexapolis, it sought to maintain its independence but fell (540 BC) under Persian rule. It had a large trade, particularly in wine, and was also noted for its medical school and other institutions of learning. One of the most famous statues of the ancient world, Aphrodite by Praxiteles, was there. In the waters off Cnidus the Athenians under Conon defeated the Spartans under Pisander in 394 BC Cnidus retained its importance in Roman times and is mentioned in the Bible (Acts 27.7; 1 Mac. 15.23).
