Insurrection of the Slaves - The First Sicilian Slave War
The servile conspiracies and servile wars, breaking out everywhere,
illustrate their management as respects police. In Italy the scenes
of disorder, which were among the immediate painful consequences of
the Hannibalic war,(13) seemed now to be renewed; all at once the
Romans were obliged to seize and execute in the capital 150, in
Minturnae 450, in Sinuessa even 4000 slaves (621).
Still worse,
as may be conceived, was the state of the provinces. At the great
slave-market at Delos and in the Attic silver-mines about the same
period the revolted slaves had to be put down by force of arms.
The war against Aristonicus and his "Heliopolites" in Asia Minor was
in substance a war of the landholders against the revolted slaves.(14)
