The particulars of the cost of church books give perhaps the best idea of prices, because these were needed by a large number of the population. Some of them were of small price, while others of a more elaborate character were of great price. In the year 1278 the bailiff of Farley spent six shillings and eightpence for books for the church, and in 1300 the monks of Ely paid six shillings for a _Decretal_, and two shillings for _Speculum Gregorianum_. In 1329 the precentor received six shillings and sevenpence, with an instruction to go to Balsham to purchase books.[15] In 1344 a Bible cost three pounds, and in 1357 a book was bought for Farley church for four shillings. Mr. Blades printed in his Life of Caxton an inventory of the library of Jean, Duc de Berri, at the château of Mohun sur Yevre, 1416. At the death of the duke the library contained one hundred and sixty-two volumes, valued at 14,909 livres. In 1443 twenty-seven volumes were purchased by the authorities of King’s Hall, Cambridge, from the executors of John Paston (who had been their steward), at a cost of £8, 17s. 4d. In 1447 the same college bought a Psalter for three shillings and eightpence, and a Donatus for one shilling. In 1449 twenty new Processionals cost All Souls College one hundred and thirteen shillings and fourpence, and in 1453 a book of Wycliffe’s was bought for seven shillings and sixpence, and one written against him for three shillings and sixpence.[16] A manuscript of 157 leaves, containing some of the works of St. Gregory, was bought in 1455 for £3, 6s. 8d. In 1459 Fastolfe’s books were highly priced; thus a fair Mass book was fixed at ten pounds, and a Holy Legend at the same sum, while two new great Antiphons were together £13, 6s. 8d. One of St. Augustine’s Epistles, containing 179 leaves, sold sometime after 1468 for £1, 13s. 4d., and about the same time one of St. Bernard’s Treatises, written on 211 leaves, was bought by Richard Hopton from the executors of a former possessor for twenty shillings. Perhaps a rather more accurate idea of the cost of manuscript books can be obtained from a consideration of the cost of materials and the pay of the scribes, and, fortunately, particulars have come down to us which allow of a comparison of the various expenses. A pocket lectionary was made in 1265 for the use of Eleanor de Montfort, Countess of Leicester, and sister of Henry III. Twenty dozen of fine vellum were purchased for the work at the price of ten shillings, and the writing, which was executed at Oxford, cost fourteen shillings. Richard du Marche, an illuminator, was paid forty shillings for illuminating a Psalter and a pair of tablets for Queen Eleanor, consort of Edward I. In the same accounts of this queen an entry is made of £6, 13s. 4d. to Adam the royal goldsmith for work done upon certain books.[17]
