The notion of moderation and measure is unknown to these enthusiasts, who easily fall into despair. In the following period, after the Norman Conquest, when manners and customs were beginning to change, the chronicler, William of Malmesbury, trying to draw a correct picture of the ancient owners of the land, is struck by the exaggerations of the Saxons' temperament. Great numbers of them are drunkards, they lead dissolute lives, and reign as ferocious tyrants; great numbers of them, too, are pious, devout, faithful even unto martyrdom: "What shall I say of so many bishops, hermits, and abbots? The island is rendered famous by the relics of native saints, so numerous that it is impossible to visit a borough of any importance without hearing the name of a new saint. Yet the memory of many has vanished, for lack of writers to preserve it!"[75] The taste for proselytism, of which the race has since given so many proofs, is early manifested. Once converted, the Anglo-Saxons produce missionaries, who in their turn carry the glad tidings to their pagan brothers on the Continent, and become saints of the Roman Church. St. Wilfrith leaves Northumberland about 680, and goes to preach the Gospel to the Frisians; St. Willibrord starts from England about 690, and settles among the Frisians and Danes[76]; Winfrith, otherwise called St. Boniface (an approximate translation of his name), sojourns in Thuringia and Bavaria, "sowing," as he says, "the evangelical seed among the rude and ignorant tribes of Germany."[77] He reorganises the Church of the Franks, and dies martyrised by the Frisians in 755. Scarcely is the hive formed when it begins to swarm. The same thing happened with all the sects created later in the English land. II. With religion had come Latin letters. Those same Anglo-Saxons, whose literature at the time of their invasion consisted in the songs mentioned by Tacitus, "carmina antiqua," which they trusted to memory alone, who compiled no books and who for written monuments had Runic inscriptions graven on utensils or on commemorative stones, now have, in their turn, monks who compose chronicles, and kings who know Latin. Libraries are formed in the monasteries; schools are attached to them; manuscripts are there copied and illuminated in beautiful caligraphy and splendid colours. The volutes and knots with which the worshippers of Woden ornamented their fibulae, their arms, the prows of their ships, are reproduced in purple and azure, in the initials of the Gospels. The use made of them is different, the taste remains the same.
