Cilicia

a maritime province in the south-east of Asia Minor. Tarsus, the birth-place of Paul, was one of its chief towns, and the seat of a celebrated school of philosophy. Its luxurious climate attracted to it many Greek residents after its incorporation with the Macedonian empire. It was formed into a Roman province, B.C. 67. The Jews of Cilicia had a synagogue at Jerusalem (Acts 6:9). Paul visited it soon after his conversion (Gal 1:21 ; Acts 9:30), and again, on his second missionary journey (Acts 15:41), "he went through Syria and Cilicia, confirming the churches." It was famous for its goat's-hair cloth, called cilicium. Paul learned in his youth the trade of making tents of this cloth.
