Heraclides Ponticus
[3][4] Heraclides' father was Euthyphron,[5] a wealthy nobleman who sent his son to study at the Platonic Academy in Athens under its founder Plato and under his successor Speusippus.Like the Pythagoreans Hicetas and Ecphantus, Heraclides proposed that the apparent daily motion of the stars was created by the rotation of the Earth on its axis once a day.Simplicius says that Heraclides proposed that the irregular movements of the planets can be explained if the Earth moves while the Sun stays still.[12] However, Heraclides seems to have been a versatile and prolific writer on philosophy, mathematics, music, grammar, physics, history and rhetoric, notwithstanding doubts about attribution of many of the works.[citation needed] Heraclides Ponticus refers with much admiration that Pythagoras would remember having been Pirro and before Euphorbus and before some other mortal.
