(Sollem perhaps understood) Livy, Herodian, St Paul; called Illyris by the Greeks, and sometimes Illyria; the country extending from the Adriatic to Pannonia thus called. Its boundaries are variously assigned. Pliny makes it extend in length from the river Arfa to the Drinius, thus including Liburnia to the west, and Dalmatia to the east: which is also the opinion of Ptolemy; who settles its limits from Mount Scardus and the Upper Mocha on the east, to Istria in the west. A Roman province, divided by Augustus into the Superior and Inferior, but of which the limits are left undetermined both by ancient historians and geographers. Illyrii the people; called Illyres by the Greeks. The country is now called Slavonia.
