"For a hero, see Neoptolemus. For a grandson of this king, see Neoptolemus II of Epirus.
Neoptolemus I of Epirus (Greek: Νεοπτόλεμος Α' Ηπείρου) (370–357 BC) was a Greek king of Epirus and son of Alcetas I, and father of Troas, Alexander I of Epirus and Queen Olympias. He was the maternal grandfather of Alexander the Great. He claimed he was a descendant of hero Achilles and King Lycomedes, while Emperor Caracalla claimed that he was a descendant of Neoptolemus I. Olympias was originally known as Polyxena and it is possible that Neoptolemus gave her that name." - (en.wikipedia.org 11.08.2021)
