This curse came to mind when I came across an article on the topic of medieval book curses. A book curse was a widely employed method of discouraging the thievery of manuscripts during the medieval period because creating a book could take years.
“A scribe would bend over his copy table, illuminated only by natural light, and spend hours each day forming letters, by hand, careful never to make an error. To be a copyist, wrote one scribe, was painful: ‘It extinguishes the light from the eyes, it bends the back, it crushes the viscera and the ribs, it brings forth pain to the kidneys, and weariness to the whole body’” (http://www.atlasobscura.com/articles/protect-your-library-the-medieval-way-with-horrifying-book-curses?utm_source=twitter&utm_medium=atlas-page). Whether they worked or not is unknown, but it was a time when people tended to believe in such curses.
Apparently, there is a book about such curses: Anathema! Medieval Scribes and the History of Book Curses by Marc Drogin. I would love to have a copy, but https://www.amazon.ca has a new copy listed at $277.94 (CAN)!
