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
We form a
strange idea of men of so great and so versatile talents as Naevius
and Plautus, if we refer such things to their free choice: this
strange and clumsy "exterritorial" character of Roman comedy
was undoubtedly due to causes very different from aesthetic
considerations. The transference of such social relations, as are
uniformly delineated in the new Attic comedy, to the Rome of the
Hannibalic period would have been a direct outrage on its civic order
and morality.
But, as the dramatic spectacles at this period were
regularly given by the aediles and praetors who were entirely
dependent on the senate, and even extraordinary festivals, funeral
games for instance, could not take place without permission of the
government; and as the Roman police, moreover, was not in the habit
of standing on ceremony in any case, and least of all in dealing with
the comedians; the reason is self-evident why this comedy, even after
it was admitted as one of the Roman national amusements, might still
bring no Roman upon the stage, and remained as it were banished to
foreign lands.
