In our way from Bologna to this place, we passed through Ravenna, a disagreeable town, though at one period the seat of empire; for, after Attila had left Italy, Valentinian chose Ravenna, in preference to Rome, for his residence, that he might always be ready to repel the Huns and other Barbarians, who poured from the banks of the Danube, and prevent their penetrating into Italy. The same reason afterwards induced Theodoric, King of the Ostrogoths, to keep his court at this city of Ravenna, after he had defeated and killed Odoacer, and assumed the title of King of Rome. The ruins of his palace and his tomb now form part of the antiquities of Ravenna; among which I shall not detain you a moment, but proceed to the river of Pisatello, the famous Rubicon,[314] which lies between this town and Rimini, and was the ancient boundary between Italy and Cisalpine Gaul.
