The object of Zoe’s anile affection was a capable man, and justified his rather humiliating elevation by good service to the empire. He beat back the Saracens from Syria and put down a Bulgarian rebellion with success. But in his last years he saw Servia, one of the conquests of Basil II., burst out into revolt, and could not quell it. He also failed in a project to reconquer Sicily from the Moors, though he sent against the island George Maniakes, the best general of the day, who won many towns and defeated the Moslems in two pitched battles. The attempt to subdue the whole island failed, and the conquests of Maniakes were lost one after the other. Michael IV., though still a young man, was fearfully afflicted with epileptic fits, which sapped his health, and so enfeebled him that he died a hopeless invalid ere he reached the age of thirty-six. The irrepressible Zoe, now again a widow, took a few days to decide whether she would adopt a son, or marry a third husband. She first tried the former alternative, and crowned as her colleague her late spouse’s nephew and namesake Michael V. But the young man proved ungrateful, and strove to deprive the aged empress of the control of affairs. When he announced his intention of removing her from the capital, the city mob, who loved the Macedonian house, and laughed at rather than reprobated the foibles of Zoe, took arms to defend their mistress. In a fierce fight between the rioters and the guards of Michael V., 3,000 lives were lost: but the insurgents had the upper hand, routed the soldiery, and caught and blinded Michael. Zoe, once more at the head of the state, now made her third marriage, at the age of sixty-two. She chose as her partner Constantine Monomachus, an old debauchee who had been her lover thirty years ago. Their joint reign was unhappy both at home and abroad. Frequent rebellions broke out both in Asia Minor and in the Balkan Peninsula. The Patzinaks sent forays across the Danube, while a new enemy, the Normans of South Italy, conquered the “theme of Langobardia,” the last Byzantine possession to the West of the Adriatic, and established in its stead the duchy of Apulia [1055]. A still more dangerous foe began also to be heard of along the Eastern frontier. The Seljouk Turks were now commencing a career of conquest in Persia and the lands on the Oxus. In 1048 the advance guard of their hordes began to ravage the Armenian frontier of the empire. But this danger was not yet a pressing one.
