“Anthropodermic bibliopegy“ is the proper term for binding books in human skin. Here are a few such books.
Harvard has a handful of these beauties. One is a 17th century tome on Spanish law by Juan Gutiérrez. It is inscribed as follows:
“The bynding of this booke is all that remains of my dear friende Jonas Wright, who was flayed alive by the Wavuma 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.”
This is @emungere‘s fault.
