Everywhere Alexander had been victorious, until even the Great King of Persia himself was utterly defeated and Alexander was seated upon his throne. He burnt the Persian palace at Persepolis in order "to take vengeance on the Persians for their deeds in the invasion of Greece, when they razed Athens to the ground and burnt down the temples. He also desired to punish the Persians for all the other injuries they had done the Greeks."[[17]]

When the news of the victories of Alexander over the Persians reached Greece, great was the amazement. For centuries, the name of the Great King had stood for all that was powerful and invincible. Though he had been driven out of Greece, he was still believed to be omnipotent in Asia. The general feeling was voiced by one of the orators, speaking of what was happening in the Athenian Assembly:

What is there strange and unexpected that has not happened in our time? We have not lived the life of ordinary men, and the things we have seen will become a tale of wonder to posterity. Is not the King of the Persians, he who channelled Athos, he who bridged the Hellespont, he who demanded earth and water of the Greeks, he who dared to write in his letters that he was lord of all men from the rising of the sun unto its setting, is he not struggling now, no longer for lordship over others, but already for his life?

Alexander had conquered the Great King and seated himself on the royal throne of Persia under the canopy of gold. But now that he had reached the summit of his ambition and was master of the greatest empire in the world, a change came over him, and he began to indulge his passions and to give himself up to all kinds of dissipation. He dressed like a Persian, which deeply offended the Greeks, who became jealous of the increasing favour the King showed to the Barbarian.

Slowly the leaders of Alexander's army began to realize the change that was taking place in their general, and though he gained in popularity with the Persians, he began to lose some of the devotion hitherto felt for him by the Greeks and Macedonians, and he was becoming estranged from his old followers. At length they realized that it was not a Greek conquest that would enslave Asia of which he dreamed, but of a world empire, in which the Barbarian would live on equal terms with the Greek. Alexander was far-seeing beyond his age, and he had learned that men whose customs are alien to those in which he had been brought up were not always to be despised, and that if he dreamed of holding the world empire he had conquered, he could only do so by treating all parts of it alike, and by encouraging intercourse between the different races which composed it. However wise this may have been, it is not difficult to understand the feeling of the older Greeks who had been educated to feel a gulf between them and the Barbarian that nothing could ever bridge. The climax of the estrangement between Alexander and his old companions came in a tragic scene at a banquet. Alexander and his friends had been drinking fast and furiously, then songs had been sung, some of which ridiculed the Macedonian officers who had recently been unfortunate in a skirmish. The older men present were offended, but Alexander laughed and had the song repeated. Clitus, who had been an old and trusted friend of the King, said angrily: "It is not well to make a jest of Macedonians among their enemies, for, though they have met with misfortunes, they are better men than those who laugh at them." Angry words passed between him and the King, until, unable to control his rage, Alexander snatched a spear from one of his guards and ran it through the body of Clitus, who fell dead to the ground. Dead silence followed this mad deed, and Alexander was sobered by the sight of the man he had loved lying dead at his feet, slain by his own hand. He drew the spear out of the body and would have killed himself with it, had the guards not interfered and led him by force to his chamber. All that night and the next day he wept bitterly and would speak to no one. At length one of his friends entered the room where he lay and said to him in a loud voice:

Is this the Alexander whom the whole world looks to, lying here weeping like a slave for fear of what men will say? It is Alexander himself who, by the right of his conquests, should be the law to decide what is right and wrong. Do you not know, Alexander, that Zeus is represented with Justice and Law on either side of him, to show that all the deeds of a conqueror are lawful and just?[[18]]

The King was soothed by these words, for he was only too ready to believe, as his friend had said, that whatever he might choose to do was right. But he was spoiled by such flattery which only increased his arrogance and made him yield more to his passions than before.

Having conquered and established an empire which extended from Greece and Macedonia in Europe across Asia to India, and which included Egypt and Libya, Alexander prepared to set out on yet another expedition to the West and to enter Arabia. He was in Babylon, and spent a long day attending to military duties. Towards evening, he left his chair of state to take a little relaxation. During his absence, a half-crazy man appeared, who, without any warning, sat himself down on the King's seat. The attendants looked on in horror at such an act, which seemed to them great impiety, but they did not dare turn him out, for suddenly superstitious fears took hold of them, and in frightened voices they whispered to each other that this could foretell nothing but some great calamity.

It was in the early summer of 323 B.C. that Alexander was ready to start on his march, but the night before he was to leave Babylon, he became ill of a fever. For a few days he was still able to attend to some business from his bed, but he grew rapidly worse. Suddenly the army realized that he was dying, and his old friends, forgetting whatever estrangement had come between them, entreated to be allowed to see him once more. They were admitted to the chamber where he lay, and passed in silence before him. He was so weak that he "could not speak, and only touched the right hand of each, and raised his head a little, and signed with his eyes." The next day Alexander was dead. Deep and awe-struck silence fell upon the city and camp for four days, and then, his generals having found amongst his papers plans for the western campaign, they endeavoured to carry them out. But they were not successful, and never again did the great army fight under one leader. Having lost the almost magical inspiration of Alexander's leadership, his successors were unable to keep the empire which he had conquered.

Almost from the moment of his death, Alexander was worshipped as a god. He was the great hero of his age, and even in his life-time, it was believed that he was half-divine. Dying so young, he was only thirty-three, possessed of great strength and god-like beauty, capable of rare generosity, brave almost to recklessness, planning conquests so far-reaching that they appealed to the imagination of everyone, given to outbursts of savage anger and vindictive rage, all these characteristics were looked upon as more than human. For more than two thousand years, the name of Alexander has been immortal in the East. There is hardly an ancient city from Babylon almost to the borders of China, that does not claim Alexander as its founder; his name still clings to old traditions and legends; to this very day the Parsees curse him for having caused the destruction of the ancient sacred Persian writings when he captured Persepolis and burnt it. Later generations of men have differed as to the lasting value of some of his work, but the name of Alexander, and the story of his hero-deeds have become a permanent possession of the imagination of mankind.
