Philosopher and historian, born c.135 bc in Apamea, Syria, but afterwards settling in Rhodes. His principal work, a History, occupied 52 books but is no longer extant. Fragments do, however, survive in the borrowings of later writers, including Caesar, Strabo, Diodorus, and Athenaeus, whose observations on the Celts are largely based upon Posidonius' ethnography. Posidonius died in c.50 bc.
