When hypothetical diagnoses are made, they are made without prejudice as to person. These should be qualified as the 'patient', himself, is not examined. I am sure that one would not accept the 'tele-diagnosis' of a doctor. If we are to accept what ancient authors say, then how many of Cicero's hands were cut off? So many times, in this Forum, one author is posed against another. One of the members of this board diagnosed me as megalomaniacal. She wouldn't bet a groat on that though. From two millenia away, one may opine, but not judge conclusively.

As for using HBO Rome as a reliable source, I think not.
