Alexander even crossed the river Jaxartes (SIR), and defeated the Scythians. Sogdiana alone of the northern provinces offered any serious resistance to his arms. Accordingly in 328 he again crossed the Oxus. He divided his army into five bodies, ordering them to scour the country in different directions. With the troops under his own command he marched against the fortress called the Sogdian Rock, seated on an isolated hill, so precipitous as to be deemed inaccessible, and so well supplied with provisions as to defy a blockade. The summons to surrender was treated with derision by the commander, who inquired whether the Macedonians had wings? But a small body of Macedonians having succeeded in scaling some heights which overhung the fortress, the garrison became so alarmed that they immediately surrendered. To this place a Bactrian named Oxyartes, an adherent of Bessus, had sent his daughters for safety. One of them, named Roxana, was of surpassing beauty, and Alexander made her the partner of his throne (B.C. 328). At Maracanda (now SAMARCAND) he appointed his friend Clitus satrap of Bactria. On the eve of the parting of the two friends Alexander celebrated a festival in honour of the Dioscuri (Castor and Pollux), though the day was sacred to Dionysus (Bacchus). The banquet was attended by several parasites and literary flatterers, who magnified the praises of Alexander with extravagant and nauseous flattery. Clitus, whom wine had released from all prudent reserve, sternly rebuked their fulsome adulation; and, as the conversation turned on the comparative merits of the exploits of Alexander and his father Philip, he did not hesitate to prefer the exploits of the latter. He reminded Alexander of his former services, and, stretching forth his hand, exclaimed, "It was this hand Alexander, which saved your life at the battle of the Granicus!" The king, who was also flushed with wine, was so enraged by these remarks, that he rushed at Clitus with the intention of killing him on the spot, but he was held back by his friends, whilst Clitus was at the same time hurried out of the room. Alexander, however, was no sooner released than, snatching a spear, he sprang to the door, and meeting Clitus, who was returning in equal fury to brave his anger, ran him through the body. But when the deed was done he was seized with repentance and remorse. He flung himself on his couch and remained for three whole days in an agony of grief, refusing all sustenance, and calling on the names of Clitus and of his sister Lanice who had been his nurse. It was not till his bodily strength began to fail through protracted abstinence that he at last became more composed, and consented to listen to the consolations of his friends, and the words of the soothsayers, who ascribed the murder of Clitus to a temporary frenzy with which Dionysus had visited him as a punishment for neglecting the celebration of his festival.
