Book excerpt: War then was the principal source of the supply of slaves, but it was not the only one. When a slave-trade is in full swing, it will be fostered in all possible ways. Brigandage and kidnapping were rife all over the Empire and in the countries beyond its borders in the disturbed times with which we are dealing. The pirates of Cilicia, until they were suppressed by Pompeius in 66, swarmed all over the Mediterranean, and snapped up victims by raids even on the coasts of Italy, selling them in the market at Delos without hindrance.
