Arrian,
The Anabasis of Alexander — Chapter XVII
(1884)
“ They also led Syrphax and his son Pelagon, and the sons of Syrphax's brothers out of the temple and stoned them to death. But Alexander prevented them making any further quest of the rest of the oligarchs for the purpose of wreaking their vengeance upon them; for he knew that if the people were not checked, they would kill the innocent along with the guilty, some from hatred, and others for the sake of seizing their property. At this time Alexander gained great popularity both by his general course of action and especially by what he did at Ephesus. ”
