Ares (Ancient Greek: Ἄρης, Árēs) is the Greek god of war and courage in Ancient Greek mythology. He is one of the Twelve Olympians, and the son of Zeus and Hera. Ares is described in Hesiod's Theogony as shield-piercing Ares and City-sacking Ares. Ares was the god of the brutal, violent and bloody side of war, and loved war for war's sake.
