Let the priests hold schools in the towns and villages, and if any of the faithful wish to entrust their children to them for the learning of letters, let them not refuse to receive and teach such children. Moreover, let them teach them from pure affection, remembering that it is written, "the wise shall shine as the splendor of the firmament," and "they that instruct many in righteousness shall shine as the stars forever and forever." And let them exact no price from the children for their teaching, nor receive anything from them, save what their parents may offer voluntarily and from affection. Another able assistant was Alcuin himself, who, after fourteen years of strenuous service at Charlemagne's court, was rewarded by the king with the office of Abbot at the monastery of Saint Martin, at Tours. There he spent the last eight years of his life in teaching, copying manuscripts, and writing letters to bishops and abbots regarding the advancement of religion and learning. The work of Alcuin in directing the copying of manuscripts has been described. In a letter to Charlemagne, soon after his appointment, he reviews his labors, contrasts the state of learning in England and Frankland, and appeals to Charlemagne for books from England to copy (R. 65). So important was his work as a teacher as well that at his death, in 814, most of the important educational centers of the kingdom were in the hands of his former pupils. Perhaps the most important of all these was Rabanus Maurus, who became head of the monastery school at Fulda. We shall learn more of him in the next chapter. [Illustration: FIG. 42. WHERE THE DANES RAVAGED ENGLAND.] NEW INVASIONS; THE NORTHMEN. Five years after Alcuin went to Frankland to help Charlemagne revive learning in his kingdom, a fresh series of barbarian invasions began with the raiding of the English coast by the Danes. In raid after raid, extending over nearly a hundred years, these Danes gradually overran all of eastern and central England from London north to beyond Whitby, plundering and burning the churches and monasteries, and destroying books and learning everywhere. By the Peace of Wedmore, effected by King Alfred in 878, the Danes were finally given about one half of England, and in return agreed to settle down and accept Christianity. The damage done by these invaders was very large, and King Alfred, in his introduction to an Anglo-Saxon translation of Pope Gregory's _Pastoral Care_ (R. 66), gives a gloomy picture of the destruction wrought to the churches and the decay of learning in England.
