Anthropodermic bibliopegy performed, or collected by medical doctors, who have access to cadavers, sometimes those of executed criminals, such as the case of John Horwood in 1821 and the Red Barn Murder in 1828. Another tradition, with less supporting evidence, is that books of erotica or the occult have been bound in human skin. The Royal College of Surgeons of Edinburgh preserves a notebook bound in the skin of the murderer William Burke after his execution and subsequent public dissection by Professor Alexander Monro in 1829. What Lawrence Thompson called "the most famous of all anthropodermic bindings" is exhibited at the Boston
Resurrectionists in the United Kingdom leading to an unfortunate situation in which corpses not legally given over for dissection were taken anyway. Documented cases of grave robbery for medical purposes can be found as far back as 1319. The 15th-century polymath Leonardo da Vinci may have secretly dissected around 30 corpses, although their provenance remains unknown. In Britain, the practice appears to have been common early in the 17th century. For example, William Shakespeare's epitaph reads "Good friend, for Jesus' sake forbear, To dig the dust enclosed here. Blessed be the man that spares these stones, And cursed be he that moves my bones" and
