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
Panegyrics as well as comic songs appear to have been uniformly
sung in Saturnian metre, of course to the pipe, and presumably in
such a way that the -caesura- in particular in each line was strongly
marked; and in alternate singing the second singer probably took
up the verse at this point.
The Saturnian measure is, like every
other occurring in Roman and Greek antiquity, based on quantity;
but of all the antique metres perhaps it is the least thoroughly
elaborated, for besides many other liberties it allows itself the
greatest license in omitting the short syllables, and it is at the
same time the most imperfect in construction, for these iambic and
trochaic half-lines opposed to each other were but little fitted
to develop a rhythmical structure adequate for the purposes of the
higher poetry.
