These letters are most likely the initials of a Roman trinomina, the three-part naming system used by male Roman citizens in ancient Rome. The trinomina consisted of three names: the praenomen (which in this case would be Titus), the 'nomen' of the family or 'gens', and the cognomen, which was originally a nickname or distinguishing title but eventually indicated a particular family branch.
