Among the other advantages of Twitter–besides finding out what famous people ate for breakfast–I discover knowledge that I find both nauseating and compelling. In his recent discourse on the history of the book at Messiah College, Anthony Grafton did not manage to get in to the arcana of book binding, else he may have filled us in a bit more on Anthropodermic Bibliopegy, a term I picked up via a tweet from the LA Times book review. From the blog the chirurgeon’s apprentice: a website devote to the horrors of pre-anaesthetic surgery:
The process of binding books using human flesh is known as ‘anthropodermic bibliopegy’. One of the earlier examples dates from the 17th century and currently resides in Langdell Law Library at Harvard University. It is a Spanish law bookpublished in 1605. The colour of the binding is a ‘subdued yellow, with sporadic brown and black splotches like an old banana’.  On the last page, there is an inscription which reads:
The bynding of this booke is all that remains of my dear friende Jonas Wright, who was flayed alive by the Wavuma [possibly an African tribe from modern-day Zimbabwe, see below illustration]on the Fourth Day of August, 1632. King Mbesa did give me the book, it being one of poore Jonas chiefe possessions, together with ample of his skin to bynd it. Requiescat in pace. 
Although it seems macabre to our modern sensibilities, this book was rebound as a way of memorialising the life of Jonas Wright. In this way, it is similar to mourning jewellery made from the hair of the deceased and worn by the Victorians during the 19th century. It is a poignant reminder of the life that has been lost.
Poignant indeed, though I doubt I’ll be asking my wife if she would like a skin-covered book to remember me by. The post goes on to note.
Anthropodermic bibliopegy reached its height of popularity during the French Revolution, when a fresh supply of bodies was always available. All sorts of books were wrapped in human skins, including a collection of poems by John Milton. One of the last known books to be bound in this fashion dates from 1893 and currently resides at Brown University. The binder did not have quite enough skin for the book, and thus split the piece into two – the front cover is bound using the outer layer of skin; the back cover and spine are bound using the inner layer of skin.
If you didn’t know better, you would think it was suede.
Gives new meaning to the idea of “Kindle Skins.”
