Romulus divided the people into three tribes, and each tribe into ten
curiæ (Dionysius, ii. 8), thus making thirty curiæ in all. Each curia
had its own priests and separate dining-room and chapel, which were
also called curiæ (_Ibid._, ii. 23). The only one of these which we
have mentioned as existing at a late period is the one connected with
the Palatine: as we have seen, it is one of the objects Tacitus gives
us for the line of the plough. Now, on the Palatine, on that line, we
have a ruin below the present surface agreeing with the time of
Romulus in its construction, to which no name has been given by the
topographers, but which we consider as the Curiæ Veteres mentioned by
Tacitus. It now supports the Auditorium of Domitian.
