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
This state of suspense and uncertainty existing in Italy when
Sulla took his departure for Greece in the beginning of 667 has been
already described: the half-suppressed insurrection, the principal
army under the more than half-usurped command of a general whose
politics were very doubtful, the confusion and the manifold
activity of intrigue in the capital. The victory of the oligarchy
by force of arms had, in spite or because of its moderation,
engendered manifold discontent.
The capitalists, painfully
affected by the blows of the most severe financial crisis which
Rome had yet witnessed, were indignant at the government on account
of the law which it had issued as to interest, and on account
of the Italian and Asiatic wars which it had not prevented.
The insurgents, so far as they had laid down their arms, bewailed
not only the disappointment of their proud hopes of obtaining equal
rights with the ruling burgesses, but also the forfeiture of their
venerable treaties, and their new position as subjects utterly
destitute of rights.
