The son of Nicagoras, Panaetius (pah-NEE-shuhs) of Rhodes attended lectures in cosmopolitan Athens. There he became the student of Diogenes of Babylon, head of an important philosophical school, the Stoa. Eventually Panaetius journeyed to Rome and gained the friendship of Scipio Aemilianus, famed victor over Carthage in the Third Punic War (149-146 b.c.e.). Panaetius even accompanied Aemilianus on a celebrated embassy to the eastern Mediterranean, visiting Egypt, Rhodes, Pergamum, and Syria. Returning to the Stoa in 129 b.c.e., Panaetius spent the rest of his life serving as its head.
