The mother school was at Deventer, a town situated at the south-west corner of the great episcopal territory of Utrecht, now the Dutch province of Ober-Yessel. It lies on the bank of that branch of the Rhine (the Yessel) which flowing northwards glides past Zutphen, Deventer, Zwolle, and loses itself in the Zuyder Zee at Kampen. A large number of the more distinguished leaders of the fifteenth century owed their early training to this great school at Deventer. During the last decades of the fifteenth century the headmaster was Alexander Hegius (1433-1498), who came to Deventer in 1471 and remained there until his death.(22) The school reached its height of fame under this renowned master, who gathered 2000 pupils around him,—among them Erasmus, Conrad Mutti (Mutianus Rufus), Hermann von Busch, Johann Murmellius,—and, rejecting the older methods of grammatical instruction, taught them to know the niceties of the Latin tongue by leading them directly to the study of the great writers of classical antiquity. He was such an indefatigable student that he kept himself awake during the night-watches, it is said, by holding in his hands the candle which lighted him, in order to be wakened by its fall should slumber overtake him. The glory of Deventer perished with this great teacher, who to the last maintained the ancient traditions of the school by his maxim, that learning without piety was rather a curse than a blessing. Other famous schools of the Brethren in the second half of the fifteenth century were Schlettstadt,(23) in Elsass, some miles from the west bank of the Rhine, and about half-way between Strassburg and Basel; Munster on the Ems, the Monasterium of the earlier Middle Ages; Emmerich, a town on the Rhine near the borders of Holland, and Altmarck, in the north-west. Schlettstadt, under its master Ludwig Dringenberg, almost rivalled the fame of Deventer, and many of the members of the well-known Strassburg circle which gathered round Jacob Wimpheling, Sebastian Brand, and the German Savonarola, John Geiler von Keysersberg, had been pupils in this school. Besides these more famous establishments, the schools of the Brethren spread all over Germany. The teachers were commonly called the _Roll-Brueder_, and under this name they had a school in Magdeburg to which probably Luther was sent when he spent a year in that town. Their work was so pervading and their teaching so effectual, that we are informed by chroniclers, who had nothing to do with the Brethren, that in many German towns, girls could be heard singing the simpler Latin hymns, and that the children of artisans could converse in Latin. § 5.
