The historian Adolfo Domínguez Monedero addresses the life and conquests of the Emperor Alexander the Great (356-323 B.C.), a disciple of Aristotle who inherited from his father, Philip II, a Greece united under the rule of Macedonia and would soon extend his territories against the Persian Empire. In his campaigns, Alexander the Great demonstrated the ferocity worthy of a descendent of Heracles, and like his ancestor Achilles he also died at an early age (at the height of his success) and left behind a life full of glories that would make him immortal in the memory of men, not only for his military feats but the discoveries and knowledge he contributed to Greek culture.
