a province lying to the north and north-west of Macedonia, along the eastern coast of the Adriatic Gulf, or Gulf of Venice. It was distinguished into two parts: Liburnia to the north, where is now Croatia, and Dalmatia to the south, which still retains the same name, and to which, as St. Paul informs Timothy, Titus went, 2 Tim. iv, 10. St. Paul says, that he preached the Gospel from Jerusalem round about to Illyricum, Rom. xv, 19.
