At last a series of insulting edicts signed by Vindex must have made some impression on [Nero] ... . Only two taunts went home: a suggestion that he was a bad lyre-player, and an insulting reference to him as 'Ahenobarbus', rather than Nero Caesar. Yet he told the Senate that he intended to renounce his adoptive name, which was now being mocked, and resume that of his family; as for his lyre-playing, he replied that he could hardly deserve Vindex's taunt (which proved the other accusations just as false) after his long and painstaking cultivation of the art; and asked a number of people from time to time whether they knew of any better performer than himself.
Of course he wasn't a bad lyre-player! He knew the lyre like anyone else. Better even. He practiced!
And, he was Nero.
So, if Vindex was wrong about his lyre-playing (evident from Nero's long hours of practice), then of course he was wrong about everything else about Nero.
Of course he was wrong. Do you know of any better performer? Well, do you?
