Olympias (in Greek, Ολυμπιάς; ca. 376–316 BC) was an Epirote princess, the fourth wife of the king Philip II of Maceon, the mother of Alexander the Great and queen consort of Macedon. A devout worshipper of the Greek god Dionysus, she was said to have kept pet snakes. Olympias apparently was originally named Myrtale (or 'Mistilis'). Later she may have been called Olympias as a recognition of Philip's victory in the Olympic Games of 356 BC. As a child she was called Polyxena and then, at marriage, Myrtale; later she was also known as Olympias and Stratonice.
