Hicetas (c. 400 BC – c. 335 BC) was a Greek philosopher of the Pythagorean School. He was born in Syracuse. Like his fellow Pythagorean Ecphantus and the Academic Heraclides Ponticus, he believed that the daily movement of permanent stars was caused by the rotation of the Earth around its axis. This trio of philosophers is reported by Calcidius to have thought that Venus and Mercury revolve around the Sun, not the Earth.
