Now that the victory was gained, the Greeks wanted to go home, and keep all the empire subject to them; but this was not Alexander’s plan.  He meant to spread Greek wisdom and training over all the world, and to rule Persians as well as Greeks for their own good.  So, though he let the Greek allies go home with pay, rewards, and honours, he kept his Macedonians, and called himself by the Persian title, Shah in Shah, King of Kings, crowned himself with the Persian crown, and wore royal robes on state occasions.  The Macedonians could not bear the sight, especially the nobles, who had lived on almost equal terms with him.  There were murmurs, and Parmenio was accused of being engaged in a plot, and put to death.  It was the first sad stain on Alexander’s life, and he fell into a fierce and angry mood, being fretted, as it seems, by the murmurs of the Macedonians, and harassed by the difficulties of the wild mountainous country on the borders of Persia, where he had to hunt down the last Persians who held out against him.  At a town called Cyropolis, a stone thrown from the walls struck him on the back of the neck, and for some days after he could not see clearly, so that some harm had probably been done to his brain.  A few days later he was foolish enough to indulge in a wine-drinking banquet, at which some flatterers began to praise him in such an absurd manner that Clitus, the son of his good foster-mother Lanika, broke out in anger at his sitting still to listen to them. “Listen to truth,” he said, “or else ask no freemen to join you, but surround yourself with slaves.”
