Lycaonia

an inland province of Asia Minor, on the west of Cappadocia and the south of Galatia. It was a Roman province, and its chief towns were Iconium, Lystra, and Derbe. The "speech of Lycaonia" (Acts 14:11 ) was probably the ancient Assyrian language, or perhaps, as others think, a corrupt Greek intermingled with Syriac words. Paul preached in this region, and revisited it (Acts 16:1 -6; 18:23; 19:1).
