Strabo, Geography

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.
