Amyntor (Ancient Greek: Ἀμύντωρ Amýntor "defender") was the name of a 4th-century BC Macedonian aristocrat, possibly of Athenian descent. He was the father of Hephaestion Amyntoros, who was a close companion and lieutenant to Alexander the Great. The full history of Hephaestion's lineage is unknown. However, Jeanne Reames[1] has suggested that he descended from Athenian expatriates to Macedon. The most popular piece of evidence pointing to such a connection is in name-tracing. "Hephaestion" is the name of the Temple of Hephaestus overlooking the Ancient Agora of Athens, near the Acropolis, a name which hardly appears at all in Macedon during this time period.
