In ancient Greece, the standard issue sword was the xiphos. The xiphos was a one-handed sword that was often used in conjunction with a shield. One of the most prominent examples of the xiphos would be the sword of Achilles, which he famously used to slay countless opponents during the Trojan War. Two-handed swords were virtually nonexistent in ancient Greece because to wield one would be to deprive yourself of a shield. Without a shield, you would become a target for archers and men with slingshots. However, I am thinking of giving my demigod character a two-handed variant of the xiphos.
