Once I spoke about this subject among a group of English intellectuals. One of them was a professor on Roman Law at one of the leading British universities. I asked him,what was the official language of the Byzantine Empire? He said, maybe sometime in the sixth or the seventh century.The Justinian Codex, the rule of law in the Byzantine Empire which was produced by Emperor Justinian, it was written in Latin.And he looked at me ,he knew that I knew already that the only original copy was found in the beginning of the sixteenth century.
