> Take Caligula as an example. We all know him as the mad emperor who supposedly once declared war on Neptune, then ordered his soldiers to attack the sea and take seashells as booty. The problem is that this story and the others like it all come from extremely late, hostile sources such as the biography Life of Caligula by Gaius Suetonius Tranquilus (lived c. 69 – after c. 122 AD) and Roman History by Kassios Dion (lived c. 155 – c. 235 AD).
Actually, I think Caligula was more trolling than insane. Reading about him, reminds me not so much of insanity, as if a 4chan poster was suddenly given absolute power.
It my view, he had the Roman Army march around collecting sea shells for the lulz.
Absolute power can be its own madness apart from lead.
