3. Anciently the Sogdiani and Bactriani did not differ much from the nomades in their mode of life and manners, yet the manners of the Bactriani were a little more civilized. Onesicritus however does not give the most favourable account of this people. Those who are disabled by disease or old age are thrown alive to be devoured by dogs kept expressly for this purpose, and whom in the language of the country they call entombers.[1016] The places on the exterior of the walls of the capital of the Bactrians are clean, but the interior is for the most part full of human bones. Alexander abolished this custom. Something of the same kind is related of the Caspii also, who, when their parents have attained the age of 70 years, confine them, and let them die of hunger. This custom, although Scythian in character, is more tolerable than that of the Bactrians, and is similar to the domestic law of the Cei;[1017] the custom however of the Bactrians is much more according to Scythian manners. We may be justly at a loss [CAS. 517] to conjecture,[1018] if Alexander found such customs prevailing there, what were the customs which probably were observed by them in the time of the first kings of Persia, and of the princes who preceded them. 4. Alexander, it is said, founded eight cities in Bactriana and Sogdiana; some he razed, among which were Cariatæ in Bactriana, where Callisthenes was seized and imprisoned; Maracanda in Sogdiana, and Cyra, the last of the places founded by Cyrus, situated upon the river Iaxartes, and the boundary of the Persian empire. This also, although it was attached to Cyrus, he razed on account of its frequent revolts. Alexander took also, it is said, by means of treachery, strong fortified rocks; one of which belonged to Sisimithres in Bactriana, where Oxyartes kept his daughter Roxana; another to Oxus in Sogdiana, or, according to some writers, to Ariamazas. The stronghold of Sisimithres is described by historians to have been fifteen stadia in height, and eighty stadia in circuit. On the summit is a level ground, which is fertile and capable of maintaining 500 men. Here Alexander was entertained with sumptuous hospitality, and here he espoused Roxana the daughter of Oxyartes. The height of the fortress in Sogdiana is double the height of this. It was near these places that he destroyed the city of the Branchidæ, whom Xerxes settled there, and who had voluntarily accompanied him from their own country. They had delivered up to the Persians the riches of the god at Didymi, and the treasure there deposited. Alexander destroyed their city in abhorrence of their treachery and sacrilege.
