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
In the desolate land of Greece, Caesar, besides other plans
such as the institution of a Roman colony in Buthrotum (opposite Corfu),
busied himself above all with the restoration of Corinth. Not only
was a considerable burgess-colony conducted thither, but a plan
was projected for cutting through the isthmus, so as to avoid
the dangerous circumnavigation of the Peloponnesus and to make
the whole traffic between Italy and Asia pass through the Corintho-
Saronic gulf.
Lastly even in the remote Greek east the monarch
called into existence Italian settlements; on the Black Sea,
for instance, at Heraclea and Sinope, which towns the Italian
colonists shared, as in the case of Emporiae, with the old inhabitants;
on the Syrian coast, in the important port of Berytus,
which like Sinope obtained an Italian constitution; and even in Egypt,
where a Roman station was established on the lighthouse-island
commanding the harbour of Alexandria.
