"Cicero, upon whose mind the advancing rays of celestial philosophy beamed with a brightness very admirable in a Pagan period of time, before the Sun of Righteousness arose, and shone forth in full splendour upon the world, informs us, in his Tusculan Questions, of a very remarkable interview between Pompey and Posidonius, which does honour to both, and of which he had an account from Pompey himself."
