Okay, here it goes: in popular culture, there is a certain definite impression of who Caius Caligula might have been. Robert Graves has (brilliantly) cemented that impression for us.
But I wonder. Almost all of the sources are Senatorial. And none that I have read is contemporary, except Josephus, and there is nothing disturbing there.
If you consider that 1) oratory in the time of the Caesars was nothing more than a mere rhetorical (and profitable) exercise, 2) Cicero's speeches show how lying to make a point was not beyond the norm, and 3) the story from the time of the Gracchi brothers until Nerva's succession was one of struggle between Senate and the equites...
I am piqued by what I read at the end of Plutarch's life of Antonius. Maybe it shouldn't matter, but I trust Plutarch more than any other of the other historians covering that period. He is so open, so fresh, and feels so honest. I've read a lot of him, and I trust him more than any Pope. And he writes: "From this marriage [Antonia and Drusus] sprang Germanicus and Claudius; of these, Claudius afterwards came to the throne, and of the children of Germanicus, Caius reigned with distinction, but for a short time only, and was then put to death with his wife and child..." [Life of Antonius, 87]
Caius can only be the infamous Caligula. Or am I wrong?
