 Under Julian the Apostate (361–363), he was ordered to rebuild the temple.To avoid doing so he fled from the city, but returned to save the Christian people from paying the penalty in his stead, and in 362 underwent very cruel treatment at the hands of the pagan mob, as recounted by Theodoret and Sozomen.He is said to have been the author of the Creed of Sirmium (351) and was counted by Tillemont as an Arian.
