Going even further back, to a person mentioned in your post, the Roman Emperor Nero was an early emo.
Here he is shown enjoying the age old emo past time of lying in bed feeling sorry for one's self.
He even wore a typical emo haircut, as seen on this statue.
Nero is of course most famous for, in typical self-centered emo fashion, playing his lyre and singing sad songs while Rome burned in AD 64.
And, like the emos who come to Landover, Nero was known to persecute Christians. It seems nothing has changed!
