When Caesar saw Brutus among his attackers, Plutarch writes, ‘he covered his head with his toga and let himself fall.’ Suetonius adds that, according to some reports, he said in Greek: ‘Kai su, teknon’ (which Shakespeare turned into the Latin ‘Et tu, Brute?’). It literally means ‘You too, child,’ but what Caesar may have intended by the words isn’t clear. Tempest cites ‘an important article’ by James Russell (1980) ‘that has often been overlooked’. Russell points out that the words kai su often appear on curse tablets, and suggests that Caesar’s putative last words were not ‘the emotional parting declaration of a betrayed man to one he had treated like a son’ but more along the lines of ‘See you in hell, punk.’
