Dirty books reveal secret lives of people living in mediaeval times

Dirty books reveal secret lives of people living in mediaeval times
For the first time a new scientific technique has allowed us into the minds and motivations of mediaeval people – through their dirty books.

A new technique invented by Dr. Kathryn Rudy, lecturer in the School of Art History at the University of St Andrews, can measure which pages in mediaeval manuscripts are the dirtiest, and therefore, the most read.

A machine called a densitometer allows the dirt contained within the pages of books centuries old to reveal the inner thoughts of our ancestors.
