Ex-Python Terry Jones in the London Times:
Nobody ever called themselves barbarians. It’s not that sort of word. It’s a word used about other people. It was used by the ancient Greeks to describe non-Greek people whose language they could not understand and who therefore seemed to babble unintelligibly: “ba ba ba”. The Romans adopted the Greek word and used it to label (and usually libel) the peoples who surrounded their own world.
The Roman interpretation became the only one that counted, and the peoples whom they called Barbarians became for ever branded — be they Spaniards, Britons, Gauls, Germans, Scythians, Persians or Syrians. And, of course, “barbarian” has become a byword for the very opposite of everything that we consider civilised.
