Catholic in his faith, and St. Leo lived on good terms with him during the four years following his election. St. Leo, dying in 461, was succeeded by Pope Hilarus, the deacon and legate who brought back a faithful report to Rome of the violent Council at Ephesus, in 449, from which he had escaped. Pope Hilarus was succeeded in 468 by Simplicius, and in 474 the emperor Leo died, leaving the throne to an infant grandson of the same name, the son of his daughter Ariadne, by an Isaurian officer Zeno, who reigned at first as the guardian of his son, and a few months afterwards came by that son's death to sole power as emperor. The worst character is given to Zeno by the national historians. His conduct was so vile, and his government so discredited by irruptions of the Huns on the Danube, and of Saracens in Mesopotamia, that his wife's stepmother Verina, the widow of Leo I., conspired against him, and was able to set her brother Basiliscus on the throne. Zeno took flight; Basiliscus was proclaimed emperor. He declared himself openly against the Catholic faith in favour of the Eutycheans. But Basiliscus was, if possible, viler than Zeno, and after twenty months Zeno was brought back. The usurper's short rule lasted from October, 475, to June, 477; exactly, therefore, at the time when Odoacer put an end to the western empire. It was upon Zeno's recovery of the throne that he received back from the Roman senate the sovereign insignia, and conferred the title of Roman Patricius on Odoacer. In the following years Zeno had much to do with Theodorich. He gave up to him part of Dacia and Moesia, and finally he made, in 484, the king of the Ostrogoths Roman consul, as a reward for the services to the Roman emperor. But, afterwards, Theodorich ravaged Zeno's empire up to the walls of Constantinople, and was bought off by a commission to march into Italy and to dethrone Odoacer. Zeno continued an inglorious and unhappy reign, full of murders, deceits, and crimes of every sort, for fourteen years after his restoration, and died in 491. Let us now pass to the ecclesiastical policy of Zeno's reign.
