It is curious how some of civilization’s greatest goods can arise from its greatest evils. Durant devotes the early part of Chapter XXXIV to discussing the difficulty of obtaining books during the Middle Ages. The greatest libraries of the time possessed some fifty volumes, and the price of a book was the year’s labor of an educated man – perhaps some $50,000 today. The poorest American today has access to greater wealth of knowledge than the best man of the Middle Ages.
What is striking about this extreme premium placed upon books is the contrast it highlights between the Middle Ages and classical Rome and Greece. In these times we hear of bibliophiles collecting vast libraries with hundreds of volumes, and of vaster public libraries such as the one at Alexandria. We hear of rich men and states who employed teams of copyists to multiply their ages’ literary wealth. Literature flowered over and over again during the long lives of these civilizations; by contrast, in the Middle Ages, Durant writes almost as if new books were unwelcome. This is because the extreme cost of a book meant that once a new book was written, it was unlikely to be copied.
What is the reason for this sharp contrast between classical and medieval civilization? As I have emphasized, the rare commodity was not literature itself – some, though not all, of the classics were available in one or a few copies – it was the actual books. Thinking about this from an economic perspective, some component of the materials necessary for the construction of books must have been extremely rare and precious: either the ink, the paper, the templates, or the labor.
Durant writes nothing to suggest that there was any shortage of ink or paper in the Middle Ages, and indeed, commercial activity seems to have generated copious amounts of records, suggesting that both of these materials were in good supply. While the templates – i.e. the books to be copied – were of course rare, it does not seem to me that their rarity alone explains the price of books. In the first place, the availability of templates should have increased exponentially as books were copied. In the second place, it would not have been necessary to expend the huge price necessary to buy a book to acquire a template; a mere loan would have been sufficient, or access to a library. Even if such loans were difficult to obtain, if just one or a few books had generous owners, these books would have been copied, all other materials being cheap, and would have proliferated over all of Europe. There are no such examples, beyond the components of the Bible.
This leaves labor. I am left to wonder if the burden of repelling barbarian raids, and expanding an infrastructure against a hostile wilderness, and under the strain of a growing population, did not make labor so valuable in the Middle Ages that clerical occupations, and in particular copying, became insupportably expensive. In classical times, the labor for copying books had almost always been slave labor; when cheap slave labor disappeared, so too did literature, until the Renaissance, with which came the printing press.
On the one hand, copying books is the luxury of a mature civilization, one that has mastered its material needs and has wealth to devote to culture. On the other hand, at least at times, the Middle Ages evidenced this wealth (in generating cathedrals and other cultural productions), and yet books did not proliferate. A mature civilization could conceivably copy books without slave labor, but the price, as mentioned above, as was true for the Middle Ages, would be the price of an educated man’s labor for the time it took to copy the book. By contrast, slave labor has the advantage of being essentially free; support the slave under whatever miserable conditions you will, and you get books. Capture an educated slave, and you have captured as many books as the slave has years of life left in him. This reduces the price of books to the price of the manual labor the slave could otherwise have been doing in that time… such a price is surely less than that of the labor of an educated man.
The answer could lie in another explanation: perhaps it is not supply that was the problem with medieval books, but demand. Perhaps there was simply no demand for books, and so they were very not made, and therefore rare. The extraordinary enthusiasm that greeted each new translation of Aristotle, and the labors of devotion and entire universities that sprang up over the meager existing knowledge of the Middle Ages, though, suggests to me that demand was not at all slack.
Slavery, of course, was a great evil. That is why we invented the printing press, and then the Internet: now, we can have our words for free, and we must only use slaves (safely stowed away offshore) to produce our clothes, food, and other fancies.
