About the name of _Attila_, there gathered cycles of traditions, Gallo-Roman or Italian, East German or Gothic, West German and Scandinavian, and Hungarian. Such traditions in Germany formed, later, the germ of the national epic, the _Nibelungen-lied_. They testify to the powerful impression which the hero of the Huns made on the memory and imagination of the different nations. GENSERIC.--_Attila_ did not see Rome; but _Genseric_, his ally, visited it with fire and sword (455). The emperor was _Petronius Maximus_, a senator, who had slain _Valentinian III._ as the penalty for a mortal offense. The weakness of Maximus as a ruler caused him to be destroyed by the populace. _Eudoxia_, the widow of Valentinian, whom Maximus had compelled to marry the author of her husband's death, had secretly implored the aid of the king of the Vandals. Once more _Leo_ showed his fearless spirit by going into the camp of the Vandal king, and interceding for Rome. He only succeeded, however, in mitigating to a limited extent the horrors that attended the pillage of the city by the fierce and greedy soldiers, the Vandals and Moors, who followed _Genseric_, For fourteen days (June 15-29, 455) Rome was given up to carnage and robbery. The conqueror carried off every thing of value that was capable of being transported. _Eudoxia_ was rudely stripped of her jewels, and with her two daughters, descendants of the great Theodosius, was conveyed away with the conqueror to Carthage. For twenty years longer _Genseric_ ruled over the Mediterranean in spite of the hostility of both empires. An expedition sent against him at the instigation of _Ricimer_, the Sueve, by the Eastern emperor _Leo_, was ill commanded by _Basiliscus_, and failed. But after the Vandal king died (477), his kingdom was torn by civil and religious disorders, and by the revolts of the Moors, and, fifty-seven years after the death of its founder, was conquered by the general of the Eastern Empire.
