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
But worst of all, naturally, was the condition of Sicily, the chosen
land of the plantation system. Brigandage had long been a standing
evil there, especially in the interior; it began to swell into
insurrection. Damophilus, a wealthy planter of Enna (Castrogiovanni),
who vied with the Italian lords in the industrial investment of his
living capital, was attacked and murdered by his exasperated rural
slaves; whereupon the savage band flocked into the town of Enna, and
there repeated the same process on a greater scale.
The slaves rose
in a body against their masters, killed or enslaved them, and summoned
to the head of the already considerable insurgent army a juggler
from Apamea in Syria who knew how to vomit fire and utter oracles,
formerly as a slave named Eunus, now as chief of the insurgents
styled Antiochus king of the Syrians. And why not? A few years before
another Syrian slave, who was not even a prophet, had in Antioch
itself worn the royal diadem of the Seleucids.(15)
