What is one example of cultural continuity between Byzantine empire and the original Roman empire?

The legal
system of the Byzantine empire was continuous with that of the earlier Roman empire. The
Justinian Code was a compilation of the opinion of earlier Latin jurists, beginning with the
earliest known records of Roman law. Opinions of famous Roman jurists such as Ulpian and Paul,
and rescripts issued by the office of the ab espistulis from the beginning of the Roman  Empire,
as well as opinions mentioning earlier praetorian edicts were incorporated in the later legal
codes. Law, as a system based on precedent, is therefore a major source of
continuity.
