Julian was the last non-Christian ruler of the Roman Empire, and attempted to revive traditional Roman religious practices at the expense of Christianity. This caused him to be remembered as Julian the Apostate by the church.

I have this coin noted down as RIC VIII 220, but as it goes I haven't verified it :) It's fairly small at 17mm and 2.51g, but that's normal for the issue.
I've always been partial to Julian, if only because he was by all accounts a clever and honest man. It's interesting to toy with the idea that things might have gone differently for Christianity or the Empire if he hadn't died after only 2 years on the throne from wounds sustained in battle against the Sasanids.
Well, yes :)
Although, his own perspective was that the Christians were simply Jewish apostates, but I suppose that is a polemic take on the matter.
