There was a certain man, named Polydamas, who was regarded as Parmenio's particular friend. Polydamas was commissioned to go to Media and see the execution performed. He was selected, because it was supposed that if any enemy, or a stranger, had been sent, Parmenio would have received him with suspicion or at least with caution, and kept himself on his guard. They gave Polydamas several letters to Parmenio, as if from his friends, and to one of them they attached the seal of his son Philotas, the more completely to deceive the unhappy father. Polydamas was eleven days on his journey into Media. He had letters to Cleander, the governor of the province of Media, which contained the king's warrant for Parmenio's execution. He arrived at the house of Cleander in the night. He delivered his letters, and they together concerted the plans for carrying the execution into effect.
