Quintus Curtius Rufus, History of Alexander 9.7.2

9.7.2

Quippe occisis quibusdam popularium, qui validiores erant, arma spectare coeperunt et Bactriana arce, quae quasi tuta neglegentius adservata erat, occupata barbaros quoque in societatem defectionis inpulerant.

While these things were doing in India, the Greek soldiers who had been recently drafted by the king into settlements around Bactra disagreed among themselves and revolted, for the stronger faction, having killed some of their countrymen who remained loyal, had recourse to arms, and making themselves masters of the citadel of Bactra, which happened to be carelessly guarded, forced even the barbarians to join their party. Their leader was Athenodorus, who had also assumed the title of king, not so much from an ambition to reign as from a wish to return to his native country along with those who acknowledged his authority. Against his life one Biton, a citizen of the same Greek state as himself, but who hated him from envy, laid a plot, and having invited him to a banquet, had him assassinated during the festivities by the hands of a native of Margiana called Boxus. The day following Biton, in a general meeting which had been convoked, persuaded the majority that Athenodorus had without any provocation formed a plot to take away his life. Others, however, suspected there had been foul play on Biton's part, and by degrees this suspicion spread itself about among the rest. The Greek soldiers, therefore, took up arms to put Biton to death should an opportunity present itself.
