As I find always interesting, we are as far to the Romans in history as the Romans were from the construction of the pyramids.
Actually its the distance in time.
Even a bit earlier if you want to consider the shift to the monotheism (not yet Christianity) of Sol as the line of demarcation.
If you want to be utterly pedantic then yes the Eastern Roman Empire survived until 1453 aka the Fall of Constantinople. So more like 1500 years in total.
Provides a nice representation of such events. Very insightful!
