Ravenna is one of those ancient cities the origin of which is lost in the mist of ages. It is, however, no guess work to say that in the days before the first unknown settlers found their way to the spot which became their permanent home, the fertile land in which it now lies embowered was a vast waste of waters and salt marshes. The first inhabitants of this dreary region drove piles into the mud, and erected their dwellings on such foundations as these afforded. Wooden piles will not last for ever, and the subsequent buildings that were put up, pulled down and replaced, have accordingly suffered in stability. When the march of Rome carried her legions north, Ravenna was encircled by a seagirt wall, and a Roman colony was established which became in Pompey's day a first-class naval station. Alive to the great strategic value of the city the Emperor Augustus constructed a new and second harbour capable of holding two hundred and fifty ships, which he named Portus Classis. This he connected by a canal with one of the estuaries of the river Po. Portus Classis lay three miles south of Ravenna, and between the two there soon sprang up a connecting link, the town of Cæsarea. The Emperor Honorius made Ravenna the capital of the West, and both he and his celebrated sister Placidia resided there.
In 493 Theodoric, king of the Ostrogoths, who had extended his conquests southwards over the Alps, captured the city, and Ravenna then became the capital of the Gothic kingdom. During his reign, a reign marked by absolute religious toleration, Italy was at peace for thirty years. Ravenna must have been at that time some miles from the coast. Jordanes, the historian, has handed down the fact that its celebrated Pineta, or Pine Forest, was in existence in Theodoric's day. Justinian, who drove out the Goths with the help of Belisarius and Narses, left the administration in the hands of the latter, who became the first Exarch. The Exarchs of Ravenna practically governed the entire Italian kingdom; even the Popes were subject to a rule which lasted one hundred and eighty-five years. In 1512 the Italian war that followed the League of Cambray brought a French army under Gaston le Foix into Romagna, and the bloodiest battle ever fought on Italian soil took place not far from the city; Gaston losing his life towards the close of the engagement at a spot marked by an obelisk.
