Ares (AIR-eez). Roman name Mars. See The Olympians for more information and another picture. Ares was the god of war. Though an immortal deity, he was bested by Heracles in battle and was almost killed when stuffed into a jar by two giants. When another hero wounded him during the Trojan War, he received scant sympathy from his father Zeus. The throne of Ares on Mount Olympus was covered in human skin.
