The Roman Emperor Julian is usually called the Apostate, for rejecting the Christian religion in which he was raised. But in a sly dig, Anatole France (1844-1924), The White Stone
, tr. Charles E. Roche (London: John Lane, 1905), p. 136, called the Emperor Constantine the Apostate, because he abandoned the pagan religion of his forefathers in favor of Christianity:
The Emperor Julian, who restored to the Empire its old religion, which had been abolished by Constantine the Apostate, is justly regarded as an opponent of the Galilean.
L'empereur Julien, qui rétablit la vieille religion de l'Empire abolie par Constantin l'Apostat, passe avec raison pour un adversaire du Galiléen.
