Before the invention of books, written knowledge was kept on scrolls. There was places
such as the library at Alexandria, Egypt which was said to contain over half a million
scrolls of knowledge collected from all of the known world. In most of man's history
the majority of people could not read or write. Consequently, books were imbued with
a mystique by the majority of people, representing knowledge that was hidden to those
who could not decipher the writings. That which was most likely to be written down
was the most important knowledge, which to early man was spiritual wisdom.
