With the greatest book-collector of this period, Richard de Bury (1287-1345), the author of the 'Philobiblon,' unfortunately, we have little to do, as his book expeditions appear to have been confined almost entirely to foreign countries. He collected books from every source open to him, and wrote of his passion with a warmth of eloquence of which even Cicero might have been proud. His most important book transaction, which comes within the purview of the present volume, relates to the gift by an Abbot of St. Albans of four volumes to De Bury, then Clerk of the Privy Seal, viz., Terence, Virgil, Quintilian, and Hieronymus against Rufinus. In addition to these, the Abbot sold him thirty-two other books for fifty pounds of silver. When De Bury became Bishop this 'gift' troubled his conscience, and he restored several of the books which had come into his possession in a perfectly honest and legitimate manner, whilst others were secured from the Bishop's executors. One of the volumes acquired in the latter manner is now in the British Museum. It is a large folio MS. on the works of John of Salisbury, and bears upon it a note to the effect that it was written by Simon (Abbot of St. Albans, 1167-1183), and another to the following effect: 'Hunc librum venditum Domino Ricardo de Biry Episcopo Dunelmensi emit Michael Abbas Sancti Albani ab executoribus predicti episcopi anno Domini millesimo ccc{o} xlv{to} circa purificationem Beate Virginis.' The catalogue of the library of the Benedictine monastery of Christ Church, Canterbury, in the Cottonian Collection, British Museum, and printed for the first time at length in Edward's 'Memoirs of Libraries' (i. 122-235), is a remarkable list of the most extensive collection of books at that time in this country. It was formed at the end of the thirteenth and beginning of the fourteenth century. This library was well furnished with works in science and history, and particularly so with the classics--Aristotle, Cicero, Lucan, Plato, Suetonius, Seneca, Terence, and Virgil. The extreme probability is that London was the highway through which the greater part of this and other early libraries passed. If, early in the fifteenth century, the book-hunter in London possessed few opportunities of purchasing books, he would have found several very good libraries which were open to his inspection. There was, for example, a very considerable collection in the Franciscan monastery, which once stood on the site now occupied by Christ's Hospital, Newgate Street. The first stone of this monastery was laid in October, 1421, amid much pomp, by the then Lord Mayor, Sir Richard Whittington, who gave L400 in books. It was covered in before the winter of 1422, and completed in three years, and furnished with books. From Stow's 'Survey' we learn that one hundred marks were expended on the transcription of the works of Nicholas de Lira, to be chained in the library, and of which cost John Frensile remitted 20s.
