You’ve heard of Nero, of course. He’s a highlight of world history in high school - the crazy Roman emperor who supposedly fiddled with a tune while the city burned to the ground. You’ve heard he was out of his mind, sure, but you have no idea exactly how nuts the last of the Julio-Claudian emperors was. Born into the twisted web of the Roman royal family, Nero was adopted by Emperor Claudius as heir to the Roman Empire. Nero distinguished himself as even crazier than any of his predecessors (which is saying something considering Caligula came before this guy).
