Julianus

I seem to have found two sources that mention Oribasius being at Julian's deathbed (John Lydus and Philostorgius) but it is interesting to note that Ammianus and Libanius do not mention him by name and Julian himself does not either (aside from the one letter addressed to him). This could possibly be indicative of their relationship being exaggerated, particularly by Eunapius. Does anyone have any thoughts on this?

Greetings all, This is my first post on the forum although I have been lurking in the shadows for some time and just haven't got round to posting until now. I am trying to find some primary sources that mention the relationship between the Emperor Julian and the physician Oribasius, specifically regarding the claim that Oribasius was at Julian's deathbed on the Persian Campaign. Does anyone know of specific passages from primary sources that mention Oribasius by name in this context? Thanks.
