In dealing with manuscripts, it is most important to distinguish between plain and illuminated manuscripts. The neglect of this caution has led to an exaggerated idea of the cost of books before the invention of printing. Instances have been given of purchases at sums equal to a king’s ransom. Hence it is supposed that books were so dear that they were quite out of the reach of any but the richest personages. But this view is erroneous, for we know that by means of the slave labour at Rome and the organised work in the monasteries, plainly written manuscripts could be obtained at a reasonable price. We know now that transcripts of MSS. can be had at a price which, if dear when compared with the price of a newly-published printed book, is by no means extravagant. What could be done at a centre of civilisation like Rome, where books were produced in large numbers and at low prices on account of the organisation of literary production, could be done at other places. There is evidence that at London, and at those seats of learning, Oxford and Cambridge, where caligraphy was a profession, books were not difficult to obtain. Every church and chapel must have had service-books. Probably during the Middle Ages, when travelling was arduous and expensive, persons living in out-of-the-way places had to pay special prices for their literary treasures. The late Professor J. Henry Middleton referred to this matter of cost in his valuable work on “Illuminated Manuscripts” (1892). After quoting from Aulus Gellius, he wrote-- “But ordinary copies of newly-published works, even by popular authors, appear to have been but little more expensive than books of this class are at the present day. The publisher and bookseller Tryphon could sell Martial’s first book of _Epigrams_ at a profit for two denarii--barely two shillings in modern value (see Mart. xiii. 3). It may seem strange that written manuscripts should not have been much more costly than printed books, but when one considers how they were produced, the reason is evident. Atticus, the Sosii, and other chief publishers of Rome, owned a large number of slaves, who were trained to be neat and rapid scribes. Fifty or a hundred of these slaves could write from the dictation of one reader, and thus a small edition of a new volume of Horace’s _Odes_ or Martial’s _Epigrams_ could be produced with great rapidity, and at very small cost” (p. 19). In the fifteenth century, even, illustrated Books of Hours were produced in France, Flanders, and Holland at a cheap rate. Mr. Middleton wrote--
