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
With the first
dawn of information as to Italy Diomedes begins to wander in the
Adriatic, and Odysseus in the Tyrrhene Sea;(18) as indeed the
latter localization at least was naturally suggested by the Homeric
conception of the legend.
Down to the times of Alexander the countries
on the Tyrrhene Sea belonged in Greek fable to the domain of the
legend of Odysseus; Ephorus, who ended his history with the year 414,
and the so-called Scylax (about 418) still substantially follow it.
Of Trojan voyages the whole earlier poetry has no knowledge;
in Homer Aeneas after the fall of Ilion rules over the Trojans
that remained at home.
