In the Alexander Mosaic from Pompeii, Alexander the Great is depicted as a heroic and idealized figure. He is shown mounted on his horse, Bucephalus, leading his troops into battle against the Persian army. Alexander is shown as young and beardless, with long flowing hair and a determined expression on his face. He is wearing a cuirass and a helmet, and is wielding a spear. His horse is rearing up, and its hooves are trampling over the bodies of fallen Persian soldiers. Alexander is shown as the epitome of a great warrior and a leader of men, and the mosaic serves as a testament to his enduring legacy.
