In the center of this sheet a demon is cleaning a barn. Olaus devotes a chapter on them in his Historia, titled "On the services performed by demons."

Demons often play tricks on people, after getting their confidence by serving them. For example, Olaus writes that "in the regions under the Seven Stars, in other words the North . . . demons, with unspeakable derision and in diverse shapes, express their encouragement to people who live in those parts; and indeed they also do them injury, that is, by overturning their houses, killing their cattle, destroying their fields, and ruining their castles and watercourses in every way" (Magnus 1996, I:182).
