Hicetas
Hicetas (around 400 BC – around 335 BC) was a Greek philosopher of the Pythagorean School. He was born in Syracuse.
He knew that daily movement of permanent stars was dependent upon the rotation of the Earth around its axis. Like the Pythagoreans Ecphantes and Heraclitus he asserted (correctly) that Venus and Mercury orbit the Sun.
