That's the original argument I made to which you were replying. The Byzantines carried on the Roman torch.
I'm not sure how a state which can trace a direct lineage of law and rulers back to Romulus is "carrying the torch".
Then again, despite being an engineer by trade, I'm a historian specializing in Late Roman Antiquity (specifically, the Eastern Empire from Leo the Isaurian to Alexios I, so I'm probably a little pedantic about it.
