“ When Artabazus had rebelled a second time and was in 353 forced to flee with Memnon into Macedonia, Mentor entered the service of the Egyptian king Nectanebus, and was sent by him with a body of Greek mercenaries to support the rebellious king Tennes (Tabnit) of Sidon against Artaxerxes III. But Tennes and Mentor betrayed the besieged town to the Persians (344 B.C.) . Tennes was killed after his treason, but Mentor gained the favour of the king. ”
