Experts at the prestigious Harvard University in Cambridge, USA, have confirmed that one of the books in the university's library is bound in human skin, reports the Sky News website.
The book, which deals with meditation - 'The Meditation of the Soul', was written in the 19th century, and a series of tests conducted on its leather covering proved with 99.9 percent certainty that it was skin taken from a human being.
According to what is written on the book, the skin belongs to a mentally ill patient, and the skin was taken from him or her when he or she was in a state of brain death.
The Harvard experts point out that although a book bound in human skin is now seen as something terrible, during the 19th century it was common and even almost acceptable. The bodies of executed criminals, for example, were donated to science and their skins were used to bind books.
The book 'Meditation of the Soul' is the only one known today to be bound in human skin.
