But Anthemius lasted no longer than the noble Majorian or the ignoble Severus. East and West had united their strength in a great expedition to put down the incessant Vandal piracies, which made all the coasts of the Mediterranean insecure.[14] It failed through the treachery of the eastern commander Basiliscus, to whose evil deeds we shall have hereafter to recur. This disaster shook the credit of Anthemius, and Ricimer also tired of his father-in-law. He went to Milan, and Rome was terrified with the report that he had made a compact with barbarians beyond the Alps. Ricimer marched upon Rome, to which he laid siege in 472. Here he was joined by Anicius Olybrius, who had married Placidia, the younger daughter of Valentinian and Eudoxia, through whom he claimed the throne, as representative of the Theodosian line. Ricimer, after a fierce contest with Anthemius, burst into the Aurelian gate at the head of troops all of German blood and Arian belief, massacring and plundering all but two of the fourteen regions. But the city escaped burning. Then Anicius Olybrius entered Rome, consumed at once by famine, pestilence, and the sword. With the consent of Leo, and at the request of Genseric, he had been already named emperor. He took possession of the imperial palace, and made the senate acknowledge him. Anthemius had been cut in pieces, but forty days after his death Ricimer died of the plague, and thus had not been able to put to death more than four Roman emperors, of whom his father-in-law, Anthemius, was the last. The Arian Condottiere, who had inflicted on Rome a third plundering, said to be worse than that of Genseric, was buried in the Church of St. Agatha in Suburra,[15] which had been ceded to the Arians, and which he had adorned. Olybrius made the Burgundian prince Gundebald commander of the forces, but died himself in October of that same year, 472, and left the throne to be the gift of barbarian adventurers. Three more shadows of emperors passed. Gundebald gave that dignity at Ravenna, in March, 473, to Glycerius, a man of unknown antecedents. In 474, Glycerius was deposed by Nepos, a Dalmatian, whom the empress Verina, widow of Leo I., had sent with an army from Byzantium to Ravenna. Nepos compelled his predecessor to abdicate, and to become bishop of Salona. He himself was proclaimed emperor at Rome on the 24th June, 474, after which he returned to Ravenna. While he was here treating with Euric, the Visigoth king, at Toulouse, Orestes, whom he had made Patricius and commander of the barbaric troops for Gaul, rose against him. Nepos fled by sea from Ravenna in August, 475, and betook himself to Salona, whither he had banished Glycerius.
