“A study of prostitutes investigated by the Inquisition in Modena reveals that although magical orations and charms were learned orally and, as one said, were kept ‘always in her heart’, those who could read were thought to be the most skilled in the art of love magic. Written copies accrued more potency than those held in oral memory, while those recorded in books were more efficacious than charms written on loose sheets. In 1600 a noted female love magician was described as reading from a big book with ‘a black cover, which is full of incantations and secrets’. One prostitute said the prayer she had written on a piece of paper was less effective than another possessed by a courtesan who obtained hers from ‘a book in which there are lots of these things’. 156 At the top of this hierarchy of texts was print, and the Modena tribunal heard several cases of prostitute love magicians requesting printers to produce versions of the prayers they knew. This may have been in part to render their power more potent, but the sale of such mass-produced prayers also proved an excellent money-spinner.”

I love this for so many reasons. I am assuming that random 156 stuck in there is an artifact of a cut-and-paste and is referencing a source. That my friends is what you call a synchronicity, which for me have always been a sign of good things.
