Healing and Curing is a book found in the library of the Temple in Ellander. Jarre describes it as "an exceptionally valuable and unique work" and tries to get Ciri to put it away. She doesn't and an interesting etching falls from between some pages.
"From between the pages suddenly slipped a large loose page with a picture of a woman, completely naked with her hair curled into ringlets, entangled in an embrace with a completely naked bearded man. Her tongue sticking out, the girl spent a long time turning the etching around, unable to make out which way up it should be. [...] Interesting, the book is called Healing and Curing. I'd like to know what diseases are cured that way." - pg.268, Blood of Elves (UK edition)
