Here's a subject I find interesting - though have yet to explore properly - notably because of the oft mentioned parallels with early Christian belief. I've often wondered if the work by Philostratus can shed any light on early Christianity - either in terms of the Apollonius story borrowing from Christianity, or even early Christianity borrowing from Apollonius. The only work on the matter I can find available online is Apollonius the Nazarene by Dr. R. W. Bernard - which I frankly thought of uploading to this site for the "Ancient Worlds" section. It does look more than slightly demogogic and a cursory glance shows little reference to anything other than other people's opinions, rather than actual primary sources. So I'm not sure it'll actually be a useful addition. Maybe later... Anyway, for some bakcground reading on the actual issue of Apollonius of Tyrana: Philostratus - Appolonius of Tyrana Apollonius of Tyrana And from here a short but intriguing comment with reference to Hadrian and Marcus Aurelius: "He wrote numerous philosophical works, which were collected by the Emperor Hadrian and preserved in his palace at Antium. The Roman emperor-philosopher Marcus Aurelius admired Apollonius, saying “From Apollonius I have learned freedom of will and understanding, steadiness of purpose, and to look to nothing else, not even for a moment, except to reason."
