Roxolani = Russians?

[Flavivs Aetivs]

Well "Royal Scythians" actually refers mainly to the Scythians who had fled east in the 3rd century AD, Herodotus suggests this is where the Huns are from (Old Sythian Tribes) but it is mainly a classicization.He is right in that this is the Area the Huns are from, but they seemed to be proto-turkic (Onogur), not Iranian.

As to the Roxolani, they were conquered by the Alans along with several other tribes by the 2nd century AD, although I don't know if that's where Alan kings came from.
