Please note that Mommsen uses the AUC chronology (Ab Urbe Condita), i.e. from the founding of the City of Rome. You can use this reference table to have the B.C. dates
Thus the necessary and stated observances due to the gods of the
community were entrusted once for all by the state to fixed colleges
or regular ministers; and the expense of sacrifices, which was
presumably not inconsiderable, was covered partly by the assignation
of certain lands to particular temples, partly by the fines.(10)
It cannot be doubted that the public worship of the other Latin,
and presumably also of the Sabellian, communities was essentially
similar in character. At any rate it can be shown that the Flamines,
Salii, Luperci, and Vestales were institutions not special to Rome,
but general among the Latins, and at least the first three colleges
appear to have been formed in the kindred communities independently
of the Roman model.
Lastly, as the state made arrangements for the cycle of its gods,
so each burgess might make similar arrangements within his individual
sphere, and might not only present sacrifices, but might also
consecrate set places and ministers, to his own divinities.
