The collection formed by Charlemagne has already been referred to, and also the provision of his will, under which, after his death, the books were to be sold and the proceeds given to the poor. Charles the Bald, with whose name it is not easy to associate intellectual activity, appears to have been a great collector of books. After his death his library was, under his directions, divided between St. Denis, Compiègne, and his son.[250] It is recorded of William the Great of Aquitaine, who died in 1030, and who was the father of the Empress Agnes, that “he had many books and read zealously therein.”[251] Count Baldwin of Guines, who died in 1205, brought together a collection of books which he had translated into the Romance tongue. Louis IX. of France was interested in the idea of bringing together a collection of devout books, and, although he did not live to carry out his plan, the manuscripts which were left by him served for the scholar Vincennes of Beauvais in the preparation of his great encyclopedia. Louis heard, during his crusade, of some sultan who had caused to be prepared transcripts of all the noted works of philosophy. This example incited the zeal of Louis, who gave directions that all the “authentic, useful, and devout books” which were to be found within his realm were to be transcribed, and the transcripts placed in the Royal Library. The collection was, however, not allowed to remain complete, as in his will Louis directed that the books should be divided between the preacher monks and the Minorites of Paris, the Abbey Royaumont, and the Dominican monks of Compiègne.[252] John, Duke of Berry, son of the Good King John, and brother of King Charles V., found opportunity, even during the troublous times which culminated with the battle of Poitiers and the imprisonment of his father, to bring together a noteworthy collection of books. It was this collection that made the beginning of the library of the Louvre, instituted by Charles V., a library for which Gilles Mallet prepared in 1373 a very complete catalogue. Barrois published in 1830, in Paris, a work devoted entirely to a description of the books collected by Prince John and his brother Charles. David Aubert, whose translation of the _History of the Emperors_ was published[253] in 1457, makes, in the preface to this history, special mention of the literary tastes of Philip, Duke of Burgundy. He says that Philip made a daily practice of having read to him ancient histories and that he kept employed a great number of skilled translators, learned historians, and capable scribes who were busied in adding to his great library. This collection of Philip appears later to have been scattered as there is no record of its preservation.
