further proof that Christians don't get science? /sarc (for the people in Loma Linda).
It isn't really a religious question, its economics. We forget in these days of mass media and high literacy that it even in the recent past it was terribly expensive to produce, distribute, and keep documents. As the article said, it would have taken a flock of sheep skin, and many many hours to create enough vellum to create the book of prayers. At the time, the book of prayers was more valuable to the monestary than the book by Archemeides, so they recycled the pages. Did they know they were getting rid of the last copy? I'd guess not.
Even in this age we lose important documents, and sometimes the reason may be that we simply produce way too much information now.
