Interesting particulars respecting the composition, binding, and expenses of Petrarch’s library will be found in M. de Nolhac’s monograph on the subject. Petrarch kept copyists in his house, whose shortcomings occasioned him much vexation. He bequeathed his library to Venice, and the Venetians are accused of having suffered it to be dispersed, but it would seem that it never reached them. We may judge from the immense number of manuscripts still existing, in spite of the wholesale destruction that occurred at various times, how large was the output in the Middle Ages. It is therefore preposterous to suppose that when books were being produced in large numbers in hundreds of monasteries in Europe they were only bought by kings or great nobles. During the troubled times of the Barons’ Wars there must have been great destruction of literary treasures, and at the Reformation, when whole libraries were destroyed and made waste-paper of, the ignorant waste was appalling. “The splendid and magnificent abbey of Malmesbury, which possessed some of the finest manuscripts in the kingdom, was ransacked, and its treasures either sold, or burnt to serve the commonest purposes of life. An antiquary who travelled through that town many years after the dissolution, relates that he saw broken windows patched up with remnants of the most valuable MSS. on vellum, and that the bakers hadn’t even then consumed the stores they had accumulated in heating their ovens.”[14] That so much is left after the wholesale raid on the monasteries is largely due to the sound antiquarian taste of John Leland, to whom we of later ages are supremely indebted. In all times of political convulsions the learning of the world stands a bad chance of escaping great loss, and we are told that twenty-five thousand manuscripts were burnt during the horrors of the French Revolution. Carelessness and the contempt felt for old books are still the great destructive forces in the East, and the Hon. Robert Curzon, who travelled in search of manuscripts, gives in his “Visits to the Monasteries in the Levant” (1849) a lively account of the irreparable losses that are constantly occurring. (See also Archdeacon Tattam’s and M. Pacho’s narratives of their negotiations with the monks of the Nitrian Desert for Syrian MSS., and the subsequent experiences of Tischendorf and Mrs. Lewis.) One of the most recent literary events is the recovery of a number of Jewish manuscripts from a _Genizah_ or storehouse of old papers and parchments at Cairo, where they were preserved indeed, but entirely neglected. The late Mr. Thorold Rogers paid considerable attention to the prices of books, and recorded many valuable facts respecting them in his important work, “History of Agriculture and Prices in England.” After commenting on some prices in the thirteenth and fourteenth centuries, he adds, “such prices indicate that written literature was not wholly inaccessible to the general public” (vol. i. p. 646).
