During the ninth and tenth centuries, so fruitful of scholars in every part of Europe, the monastic schools may be said to have reached their highest development. Of those north of the Alps we may mention Fulda, Old and New Corby, Richneau, and St. Gall, though there were a great many others of nearly equal extent and reputation. Fulda, as we have seen, was founded by Strum, a pupil of St. Boniface, who adopted the Benedictine rule. After its founder, its greatest teacher was Rabanus, a pupil of Alcuin, who assumed the charge of the school about 813. His success in teaching was so great that it is said that all the German nobles sent their sons to be educated by him, and that the abbots of the surrounding monasteries were eager to have his students for professors. He taught grammar so thoroughly that he is mentioned by Trithemius as being the first who indoctrinated the Germans in the proper articulation of Latin and Greek. His course embraced all sacred and profane literature, science, and art; yet he still found time to compose, and afterward, when Archbishop of Mentz, to publish his treatise _De Institutione Clericorum_. Among his pupils were Strabo, author of the _Commentaries on the Text of Scripture_; Otfried, called the father of the Tudesque, or German literature; Lupus, author of _Roman History_; Heinie, author of the _Life of St. Germanus_; Regimus, of Auxerre; and Ado, compiler of the _Martyrology_. While those great scholars were teaching and writing, it is worth our while to inquire what the lesser lights of the monastery were doing. Here is the picture: {56}
