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
It is impossible to doubt that Greek influences exercised
a powerful effect on this remodelling of the Roman community, but
it is equally impossible to demonstrate the mode or the degree of
their operation. It has already been observed that the Servian
military constitution is essentially of an Greek type;(17)
and it will be afterwards shown that the games of the Circus were
organized on an Greek model.
The new -regia-with the city hearth
was quite a Greek πρυτανεῖον, and the round temple of Vesta,
looking towards the east and not so much as consecrated by the
augurs, was constructed in no respect according to Italian, but
wholly in accordance with Greek, ritual. With these facts before
us, the statement of tradition appears not at all incredible that
the Ionian confederacy in Asia Minor to some extent served as a model
for the Romano-Latin league, and that the new federal sanctuary on
the Aventine was for that reason constructed in imitation of the
Artemision at Ephesus.
