Alexander's march from Susa to Persepolis was less a march than a triumphal progress. He felt the pride and elation so naturally resulting from success very strongly. The moderation and forbearance which had characterized him in his earlier years, gradually disappeared as he became great and powerful. He was intoxicated with his success. He became haughty, vain, capricious, and cruel. As he approached Persepolis, he conceived the idea that, as this city was the capital and center of the Persian monarchy, and, as such, the point from which had emanated all the Persian hostility to Greece, he owed it some signal retribution. Accordingly, although the inhabitants made no opposition to his entrance, he marched in with the phalanx formed, and gave the soldiers liberty to kill and plunder as they pleased.
