 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).Based on Demosthenes's "Against Aristocrates", Python of Byzantium was identified with Python of Aenus the latter of which killed King Cotys I of the Odrysian Kingdom.
