Alexander at the Battle of Issus In this first-century-B.C.E. mosaic from the Roman city of Pompeii, Alexander the Great (left), bareheaded and wearing a breastplate, charges King Darius III (right), who is standing in a chariot. Alexander was widely admired by Romans, and this mosaic portrays him in a heroic light, just at the point in the battle when Darius turns to flee from the attack. (C. M.
