Julian the Apostate

Julian (Latin: Flavius Claudius Julianus; 331 – 26 June 363) was the Caesar of the West from 355 to 360 and Roman emperor from 361 to 363, as well as a notable philosopher and author in Greek. His rejection of Christianity, and his promotion of Neoplatonic Hellenism and persecution of Christians, caused him to be remembered as Julian the Apostate in the Christian tradition. (Wikipedia)
