I agree - to a point. I call him the last of the Roman generals because he is probably the last general that earlier generations, especially in the Principate, would acknowledge as being their descendant, and was probably the last natural Latin speaker that rose to high rank. After him, and especially with Narses, there is a distinct switch to a more Eastern culture, despite the fact that they thought of themselves as 'Romans'. I can't really believe that, for instance, Augustus, Caesar or Trajan would have been impressed with the idea of an eunuch at the head of the Imperial armies.
