Book excerpt: Although written over four hundred years after Alexander's death, Arrian's account of the man and his achievements is the most reliable we have. Arrian's own experience as a military commander gave him unique insights into the life of the world's greatest conqueror. He tells of Alexander's violent suppression of the Theban rebellion, his defeat of Persia and campaigns through Egypt and Babylon - establishing new cities and destroying others in his path. While Alexander emerges as a charismatic leader, Arrian succeeds brilliantly in creating an objective portrait of a man of boundless ambition, who was exposed to the temptations of power.
