赫拉克利德斯·彭提烏斯（ Heraclides Ponticus）（公元前四世紀(jì)）,他是柏拉圖的弟子,后來(lái)成了亞里土多德的密友.
Heraclides Ponticus (387 - 312 BCE),also known as Heraklides,was a Greek philosopher who lived and died at Heraclea,now Karadeniz Ereğli,Turkey.He has frequently been hailed as the originator of the heliocentric theory.This is now generally doubted.
Heraclides' father was Euthyphron,a wealthy nobleman who sent him to study at the Academy in Athens under its founder Plato and under his successor Speusippus,though he also studied with Aristotle.According to the Suda,Plato,on his departure for Sicily in 360 BCE,left his pupils in the charge of Heraclides.Speusippus,before his death in 339 BCE,had chosen Xenocrates as his successor but Xenocrates narrowly triumphed in an ensuing election against Heraclides and Menedemus.
A punning on his name,dubbing him Heraclides "Pompicus," suggests he may have been a rather vain and pompous man and the target of much ridicule.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.It appears that he composed various works in dialogue form.The main source of this biographical welter is the collection by Diogenes Laërtius.
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.According to a late tradition,he also believed that Venus and Mercury revolve around the Sun.This would mean that he anticipated the Tychonic system,an essentially geocentric model with heliocentric aspects.However,the tradition is almost certainly due to a misunderstanding,and it is unlikely that Heraclides,or his Pythagorean predecessors,advocated a variation on the Tychonic system.
Of particular significance to historians is his statement that fourth century Rome was a Greek city.
