A review from the London Review of Books of The Lives of Caesars, originally written during the Roman Empire by Suetonius.  It includes lots of rumors and stories of the vices of a dozen Roman emperors, including Caesar, Nero and Caligulia.  I suppose it was the Epstein files of its era.

Interesting to note that Caligulia was murdered at age 28, less than four years into his reign.  Nero lasted a bit longer, taking power at 16 but slitting his own throat at 30 after being declared an enemy of the state.
