The object of this colony was to assist the Trachinian s, a tribe of the Malians , in their struggle against the Oetaeans . Thucydides also tells us that the Sparta ns thought the town would lie conveniently for the purposes of the war with Athens . From Heraclea the Spartans could ready a fleet to annoy Euboea , and the town would be a useful station on the road to Thrace . Accordingly the Spartans sent Leon king of Sparta Leon , Alcidas , and Damagon to found the town, and invited any other Dorians that wished to come and settle. However, soon after the town was founded, things began to go quite badly. The Thessalians, fearful that the new colony would grow powerful and begin to usurp their influence in the area, began to make continuous sorties upon the settlement. This, combined with the harsh and unjust rule of the Spartan governors, soon depleted the town of inhabitants, and discouraged others from joining. Six years after its founding a battle took place between the inhabitants of Heraclea and the assembled forces of the Aenianes , Dolopes , Malians , and Thessalians who were directly menaced by the colony.

Other uses Python disambiguation Python Python of Byzantium was an ancient Greek statesman and former student of Isocrates . In 346 BC, he appears to have participated in negotiations at Pella that resulted in the Peace of Philocrates . In 343 BC, Python represented Philip II of Macedon in Athens with an offer to alter the overall treaty. Hegesippus remarked that Python oratorically adhered to the instructions of his teachers in Athens implying that Isocrates was a supporter of Macedon since he retained some influence over Python . ref Natoli, Anthony Francis. The Letter of Speusippus to Philip II Introduction, Text, Translation and Commentary with an Appendix on the Thirty first Socratic Letter Attributed to Plato . Franz Steiner Verlag, 2004, ISBN 3515083960, p. 54. Among the pupils and former pupils of Isocrates three are known to have been associated with Philip. The first was Python of Byzantium, who appears to have been at Pella in 346 and may have played a role in the negotiations around the Peace of Philocrates. Then in 343, as we have seen, Python represented Philip in Athens with an offer to revise the Peace of Philocrates. On this occasion Hegesippus remarked pointedly that the orator was following the instructions of his schoolmasters in Athens. It is clear from this remark that Isocrates could be portrayed to the Athenian public as an outright supporter of Philip who retained some influence with his former pupil, Python. ref Based on Demosthenes s Against Aristocrates , Python of Byzantium was identified with Python of Aenus the latter of which killed King Cotys I Odrysian Cotys I of the Odrysia Odrysian Kingdom . However, it is highly unlikely that both names are attributed to one individual. ref Natoli, Anthony Francis.

Euphraeus lang grc fl. c. 4th century BCE d. ca. 342 BCE 341 BCE was a philosophy philosopher and student of Plato from the town of Oreus in northern Euboea . He appears to have been active in politics in addition to his speculative studies, being first an adviser to Perdiccas III of Macedon and then an opponent of Philip II of Macedon Philip II and his supporters in Oreus. Information regarding his life is scant, however, and few facts about it are mentioned in more than one source. He appears in the Fifth Letter Plato Fifth Letter of Plato , Demosthenes Demosthenes Third Philippic , and Athenaeus Athenaeus Deipnosophistae which repeats the information about him contained in the now lost Historical Notes by Carystius Carystius of Pergamum . Life None of the sources that mention him say anything about his family or early life. Most of what is known about him involves his political activity. Little is said about Euphraeus in the Fifth Letter of Plato beyond his aptitude for political philosophy , and the letter s authenticity has been challenged. ref Bury, Epistle V, 499. ref The letter commends Euphraeus to Perdiccas III of Macedon Perdiccas III , monarch king of Macedon . This story, at least, is supported by Carystius, who cites a letter supposedly by Speusippus Plato Plato s nephew and successor as head of the Academy that Philip II of Macedon Philip II should cease slandering Plato because he owes him his monarchy kingship , if rather backhandedly.
