As he fell, Caesar cried out in Greek to Brutus, ‘You too, child’, which was either a threat (‘I’ll get you, boy!’) or a poignant regret for the disloyalty of a young friend (‘You too, my child?’), or even, as some suspicious contemporaries imagined, a final revelation that Brutus was, in fact, his victim’s natural son and that this was not merely assassination but patricide. The famous Latin phrase ‘Et tu, Brute?’ (‘You too, Brutus?’) is an invention of Shakespeare’s.
