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
He felt full well, and in his epitaph expressed, what he had
been to his nation:
-Immortales mortales si foret fas fiere,
Flerent divae Camenae Naevium poetam;
Itaque, postquam est Orci traditus thesauro,
Obliti sunt Romae loquier lingua Latina.-
Such proud language on the part of the man and the poet well befitted
one who had witnessed and had personally taken part in the struggles
with Hamilcar and with Hannibal, and who had discovered for the
thoughts and feelings of that age--so deeply agitated and so
elevated by mighty joy--a poetical expression which, if not exactly
the highest, was sound, adroit, and national. We have already
mentioned(31) the troubles into which his licence brought him with
the authorities, and how, driven presumably by these troubles from
Rome, he ended his life at Utica.
