By the following year, 452, Attila had collected another army, and now directed his march towards Italy. This new invasion was so unexpected that the passes of the Alps were left undefended, and the Huns reached the rich and populous city of Aquileia, on the northern shore of the Adriatic, without meeting any opposition. After a siege of three months, they took and razed it to the ground so completely that it was never rebuilt, and from that day to this only a few piles of shapeless stones remain to mark the spot where it stood. The inhabitants who escaped took refuge upon the low marshy islands, separated from the mainland by the lagoons, and there formed the settlement which, two or three hundred years later, became known to the world as Venice. Attila marched onward to the Po, destroying everything in his way. Here he was met by a deputation, at the head of which was Leo, the Bishop (or Pope) of Rome, sent by Valentinian III. Leo so worked upon the superstitious mind of the savage monarch, that the latter gave up his purpose of taking Rome, and returned to Hungary with his army, which was suffering from disease and want. The next year he died suddenly, in his wooden palace at Tokay. The tradition states that his body was inclosed in three coffins, of iron, silver and gold, and buried secretly, like that of Alaric, so that no man might know his resting-place. He had a great many wives, and left so many sons behind him, that their quarrels for the succession to the throne divided the Huns into numerous parties, and quite destroyed their power as a people. [Sidenote: 455. GEISERICH TAKES ROME.] The alliance between Aëtius and the Visigoths ceased immediately after the great battle. Valentinian III., suspicious of the fame of Aëtius, recalled him to Rome, the year after Attila's death, and assassinated him with his own hand. The treacherous Emperor was himself slain, shortly afterwards, by Maximus, who succeeded him, and forced his widow, the Empress Eudoxia, to accept him as her husband. Out of revenge, Eudoxia sent a messenger to Geiserich, the old king of the Vandals, at Carthage, summoning him to Rome. The Vandals had already built a large fleet and pillaged the shores of Sicily and other Mediterranean islands. In 455, Geiserich landed at the mouth of the Tiber with a powerful force, and marched upon Rome. The city was not strong enough to offer any resistance: it was taken, and during two weeks surrendered to such devastation and outrage that the word _vandalism_ has ever since been used to express savage and wanton destruction. The churches were plundered of all their vessels and ornaments, the old Palace of the Cæsars was laid waste, priceless works of art destroyed, and those of the inhabitants who escaped with their lives were left almost as beggars.
