Well, if you mean Byzantine Empire (East Roman Empire with the Constantinople as a capitol) then absolutely massive amount of things shared it's time with it because it has fallen in 1453, even Columbus shared the planet with it.
But at this point, maybe incorrectly but surely, 'Roman Empire' is synonymous with antiquity so the republic and early empire, I think that even if year 495 counts here then it's borderline
