The work of Otto I was skilfully done, since it survived the follies of his son and grandson. For twenty years after his death (973) the titular rulers of the Empire were boys and women-regents. At Rome, in Germany, on the western and eastern frontiers all the beaten factions and humiliated rivals plucked up courage to make another bid for victory. The old Empress Adelaide, and her daughter-in-law the Empress Theophano, divided or disputed the control of the administration until 991; from that date till 998 the elder woman, freed from interference by the death of Theophano, exercised a great though a declining influence. Neither Empress was competent to handle the singular difficulties of the situation. Adelaide, though true to the German ambitions of her husband, was guided by personal prejudice in the selection of her ministers. Theophano, a woman of remarkable abilities and attainments, despised the monotonous intricacies of German politics, encouraged both her husband and her son to regard Italy as the worthiest field for the activities of an Emperor, and in Italy looked rather to Rome and the South than to Lombardy. It was the church party, both in Germany and in Lombardy, which in these years kept the subjects of the Empire true to their allegiance. The German dukes were less disinterested. But the precedents which Otto I had established proved invaluable when his son was required to deal with a rebellion, or had the opportunity of appointing to a vacant dukedom. The blame for the chimerical ambitions of Otto II and Otto III is usually thrown upon Theophano, that brilliant missionary of Byzantine culture and Byzantine political ideas. But the influence which perverted the judgement of these Emperors, until they became a byeword in Europe, was something more impalpable than the will-force of a domineering woman. They were born into the misty morning twilight of the medieval renaissance, of an age when intellectual curiosity was awakening, when philosophy, the sciences and Latin literature were studied with a lively but uncritical enthusiasm, when the rhetorician and the sophist were the uncrowned kings of intelligent society. The philosophy was little more than school-logic, derived at second or third hand from Aristotle, the science a grotesque amalgam of empiricism and tradition. The Latin classics, apart from their use as a source of tropes and commonplaces, only served to inspire a superstitious and uncomprehending reverence for ancient Rome. Of this new learning Otto II and his son were naive disciples. They could not sufficiently admire the encyclopaedic Gerbert, the most fashionable and incomparably the ablest teacher of their day. Otto II and his court listened patiently for hours while Gerbert disputed with a Saxon rival concerning the subdivisions of the genus philosophy. Otto III invited Gerbert to come to court and cure him of "Saxon rusticity"; he deluged the complaisant tutor with Latin verses,
