Peithagoras
2. A soothsayer, brother of Apollodorus of Am phipolis, who was one of the generals of Alexander the Great. According to Aristobulus (apud Arr. Anab. 7.18), Apollodorus, having joined the king on his return from his Indian expedition and accompanies him to Ecbatana, imagined that he had grounds for dreading his displeasure, and wrote therefore to Peithagoras at Babylon, to inquire whether any danger threatened him from Alexander or Hephaestion. The answer was that He had nothing to fear from Hephaestion, who (so the victims portended) would soon be removed out of his way. The next day Hephaestion's death took place (B. C. 324,) and not long after Apollodorus received the same message from Peithagoras respect to Alexander. Here again the event justified the prediction (Plut. Alex. 73).
