The chapel of Saint Caius, with its heathenish altar, brings our thoughts back to the long walls below it, the walls which yoked the ancient Salona to the deeper sea. It must not be forgotten that, in the days of its greatness, Salona was one of the chief ports of the Hadriatic, the greatest on its own side of it. After shifting to and fro from one port to another, that position has come back, if not to Salona itself, yet to its modern representative. If we distinguish the Hadriatic from the Gulf of Trieste, Spalato is undoubtedly its chief port; but the smallness of Spalato, as compared with the greatness of ancient Salona, is a speaking historical lesson. We see the difference between the place in Europe which is held by the Illyrian lands now and the place which they held in the days of the Roman peace. Then Salona was one of the chief cities of the Roman world, placed on one of the most central sites in the Roman world, the chief port of one of the great divisions of the Empire, and one of the main highways between its eastern and western halves. Such could be the position of a Dalmatian city when Dalmatia had a civilized mainland to the back of it. Salona therefore kept up its position as long as the Empire still kept any strength on its Illyrian frontier. It played its part in both the civil wars. Cæsar himself enlarges on the strength of the city--"oppidum et loci natura et colle munitum." In after-times it was a special object of the regard of its own great citizen, who took up his abode so near to its neighbourhood. According to Constantino Porphyrogenitus, Salona was pretty well rebuilt by Diocletian. Its importance went on in the time of transition, as is witnessed by the growth of its ecclesiastical buildings, and by the high position held by its bishopric. Like the rest of the neighbouring lands, it passed under the dominion, first of Odoacer and then of Theodoric, and it was the first place which was won back to the Empire in the wars of Justinian. Lost again and won back again, it appears throughout those wars as the chief point of embarcation for the Imperial armies on their voyages to Italy. This was the last century of its greatness; in the next century the modern history of Illyria begins. The Slaves were moving, and the Avars were moving with them. Salona fell into the hands of these last barbarians; it was ruined and pillaged, and sank to the state in which it has remained till our own time. Since the seventh century Salona has ceased to rank among the cities of the earth, but the house which had been raised by its greatest citizen stood ready hard by to supply a shelter to some at least of its homeless inhabitants. Things were wholly turned about on the bay of Salona and on the neighbouring peninsula. Down to the days of Heraclius, Salona had been a great city, with the vastest house that one man ever reared standing useless in its neighbourhood. From his day onwards the house grew into a city, and the city became a petty village, where, of all the places along that historic coast, the traveller finds least to disturb him in the pious contemplation of ruins. The only danger is that his meditations may be broken in upon by sellers of coins and scraps of all ages, dates, and values. Coins at Salona hardly need the process once known at the Mercian Dorchester as "going a-Cæsaring." Cæsars seem to be picked up from under and off the ground with much less trouble than hunting for truffles. And even he who is no professed numismatist or collector of gems will be pleased to give a few _soldi_, perhaps even for a very clear image and superscription of "Constantinus Junior Nob[ilissimus] C[æsar]," much more for any image and superscription of Jovius himself. It may have neither rarity nor value in the eyes of the numismatically learned; but it is something to carry away from Salona itself the head of the foremost local worthy in Salona's long annals.
