Phidias or Pheidias was an Ancient Greek sculptor, painter, and architect, active in the 5th century BC. His Statue of Zeus at Olympia was one of the Seven Wonders of the Ancient World. Phidias also designed the statues of the goddess Athena on the Athenian Acropolis, namely the Athena Parthenos inside the Parthenon, and the Athena Promachos, a colossal bronze which stood between it and the Propylaea, a monumental gateway that served as the entrance to the Acropolis in Athens. Phidias was the son of Charmides of Athens. The ancients believed that his masters were Hegias and Ageladas.
