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
Above all, lyrical, didactic, and epigrammatic poetry found but feeble
representation. The religious festival chants--as to which the annals
of this period certainly have already thought it worth while to
mention the author--as well as the monumental inscriptions on temples
and tombs, for which the Saturnian remained the regular measure,
hardly belong to literature proper. So far as the minor poetry makes
its appearance at all, it presents itself ordinarily, and that as
early as the time of Naevius, under the name of -satura-.
This term
was originally applied to the old stage-poem without action, which
from the time of Livius was driven off the stage by the Greek drama;
but in its application to recitative poetry it corresponds in some
measure to our "miscellaneous poems," and like the latter denotes not
any positive species or style of art, but simply poems not of an epic
or dramatic kind, treating of any matters (mostly subjective), and
written in any form, at the pleasure of the author.
