6.16.5

ὁ δὲ καὶ ἄλλην πόλιν ἐν τούτῳ ἀποστᾶσαν εἷλεν καὶ τῶν Βραχμάνων, οἳ δὴ σοφισταὶ τοῖς Ἰνδοῖς εἰσιν, ὅσοι αἴτιοι τῆς ἀποστάσεως ἐγένοντο ἀπέκτεινεν. ὑπὲρ ὧν ἐγὼ τῆς σοφίας, εἰ δή τίς ἐστιν, ἐν τῇ Ἰνδικῇ ξυγγραφῇ δηλώσω.

He then advanced against Sambos, whom he had appointed satrap of the Indian mountaineers, and who was reported to have fled on hearing that Mousikanos had been pardoned by Alexander, and was ruling his own land, for he and Mousikanos were on hostile terms. But when Alexander approached the city called Sindimana, which formed the metropolis of the country of Sambos, the gates were thrown open on his arrival, and the members of the household of Sambos with his treasure (of which they had reckoned up the amount) and his elephants went forth to meet him. Sambos, these men informed him, had fled, not from hostility to Alexander, but from fears to which the pardon of Mousikanos had given rise. He captured besides another city, which had at this time revolted, and he put to death all those Brachmans who had instigated the revolt. These Brachmans are the philosophers of the Indians, and of their philosophy, if so it may be called, I shall give an account in my work which describes India.
