| One of the chief causes of the prevailing ignorance was the scarcity of books. The old libraries were destroyed by ruthless barbarians and the ravages of war. After the conquest of Alexandria by the Saracens, the cultivation and exportation of Egyptian papyrus ceased, and parchment or vellum, which took its place, was so expensive that complete copies of the Bible cost as much as a palace or a farm. King Alfred paid eight acres of land for one volume of a cosmography. Hence the custom of chaining valuable books, which continued even to the sixteenth century. Hence also the custom of erasing the original text of manuscripts of classical works, to give place to worthless monkish legends and ascetic homilies. Even the Bible was sometimes submitted to this process, and thus the word of God was made void by the traditions of men. | |
