Hocus Pocus Junior

Partly a reminder to myself to read it another time, but also of interest from BoingBoing: a really old example of plagiarism.

Although it's the earliest book devoted to magic as a performing art, it apparently takes its text almost exactly from a 1584 book called The Discoverie of Witchcraft. The Witchcraft book was meant to be a debunking text, proving to people that witches didn't exist and, thus, that we shouldn't go about condemning other people for witchcraft. Hocus Pocus Junior took the chapters on sleight of hand and slightly (heh) reworked them as an instructional manual.
