>800 years since the founding of the empire
STOP.

Not sure about it being 800 years since the founding of the empire, but ~800 years from the founding of Rome (to the time where Lucius operates) would put its history to the reign of Hadrian, which is quite close. An inane point to be pedantic about, really.
