The breadth of Illyricum^ at its widest part is 325 miles, 

 and its length from the river Arsia to the river Driuius 

 530 ; from the Drinius to the Promontory of Acroceraunia 

 Agrippa states to be 175 miles, and he sa^s that the entire 

 circuit of the Italian and lUyrian Gulf is 1700 miles. In 

 this Gulf, according to the limits which we have drawn, 

 are two seas, the Ionian^ in the first part, and the Adiiatic, 

 which runs more inland and is called the Upper Sea. 



CHAP. 30. — ISLANDS OP THE IONIAN SEA AND THE ADEIATIC. 



In the Ausonian Sea there are no islands worthy of 

 notice beyond those which we have already mentioned, and 

 only a few in the Ionian ; those, for instance, upon the Cala- 

 brian coast, opposite Brundusium, by the projection of which 

 fi harbour is formed ; and, over against the Apulian coast, 

 Diomedia^, remarkable for the monument of Diomedes, and 

 another island called by the same name, but by some Teutria. 



* Ajasson remarks here that the name of Ulyricum was very vaguely 

 used by the ancients, and that at different periods, different countries 

 were so designated. In Pliny's time that region comprised the country 

 between the Arsia and the mouth of the Dnlo, boimding it on the side 

 ot Macedonia. It would thus comprehend a part of modem Camiola, 

 with part of Croatia, Bosnia, Dalmatia, and Upper Albania. In later 

 times this name was extended to Noricimi, Pannonia, Moesia, Dacia., 

 Macedonia, Thessalia, Achaia, Epirus, and even the Isle of Crete. 



* Here meaning that part of the Mediterranean wliich Hes between 

 Italy and Greece south of the Adriatic. In more ancient times the 

 Adriatic was included in the Ionian Sea, which was probably so called 

 from the Ionian colonies which settled in Cephallenia and the other 

 islands on the western coast of G-reece. 



3 More properly " Diomedese," being a group of small islands off the 

 coast of Apulia now called I sole di Tremiti, about eighteen miles from 

 the mouth of the Fortore. They were so called from the fable that here 

 the companions of Diomedes were changed into birds. A species of sea- 

 fowl (which PUny mentions in B. x. c. 44)) were said to be the descend- 

 ants of these Greek sailors, and to show a great partiality for such 

 persons as were of kindred extraction. See Ovid's Metamorphoses, 

 B. xiv. 1. 500. The real nvunber of these islands was a matter of dispute 

 with the ancients, but it seems that there are but three, and some mere 

 rocks. The largest of the group is the island of San Domenico, and the 

 others are San Nicola and Caprara. The small island of Pianosa, eleven 

 miles N.E., is not considered one of the group, but is not improbably 

 the Teutria of PMny . San Domenico was the place of banishment of Julia, 

 the Hcentious daughter of Augustus.
