Julian the Apostate

Thou hast conquered, Galilean!

Alleged famous last words of Imperator Caesar Flavius Claudius Julianus Augustus, as first attributed to him a century after his death (June 26, A.D. 363, from wounds fighting the Sassanid Empire in the Battle of Samarra) by Theodoret in his Ecclesiastical History, Book III, Ch. 20. The reference, of course, is to Jesus of Nazareth; Julian, a neoplatonic philosopher, was the last pagan (non-Christian/anti-Christian) Roman emperor, nephew to Constantine the Great.
