§ 100.2. =Italy= produced during the second half of the century many theologians eminent and important in their day. =Atto=, bishop of Vercelli, who died about A.D. 960, distinguished himself by his exegetical compilations on Paul’s epistles, and as a homilist and a vigorous opponent of the oppressors of the church during these rough times. Still more important was his younger contemporary =Ratherius=, bishop of Verona, afterwards of Liège, but repeatedly driven away from both, who died A.D. 974. A strict and zealous reformer of clerical morals, he insisted upon careful study of the Bible, and wrought earnestly against the unblushing paganism of the Italian scholars of his age as well as against all kinds of hypocrisy, superstition, and ecclesiastical corruptions. This, and also his attachment to the political interests of the German court, exposed him to much persecution. Among his writings may be named _De contemptu canonum_, _Meditationes cordis_, _Apologia sui ipsius_, _De discordia inter ipsum et clericos_.--In =France= we meet with =Odo of Clugny=, who died in A.D. 942, famed as a hymn writer and homilist, and, in his _Collationum Ll. iii._, as a zealous reprover of the corrupt morals of his age. In England and France, =Abbo of Fleury= taught toward the end of the century. From England, where he had been induced to go by St. Dunstan, he returned after some years to his own cloister of Fleury, and by his academic gifts raised its school to great renown. He wrote on astronomy, mathematics, philosophy, and history. He also composed a treatise on dialectics, in which he makes his appearance as the first and most eminent precursor of the Schoolmen. Chosen abbot of his monastery and exercising strict discipline over his monks, he suffered a martyr’s death by the hand of a murderer in A.D. 1004.--=Gerbert of Rheims=, afterwards Pope Sylvester II. (§ 96, 3, 4), during his active career lived partly in France, partly in Italy. Distinguished both for classical and Arabic scholarship, he shone in the firmament of this dark century as it was passing away († A.D. 1003) like a star of the first magnitude in theology, mathematics, astronomy, and natural science, while by the common people he was regarded as a magician. Under him the school of Rheims reached the summit of its fame. § 101. THE ELEVENTH CENTURY.
