Adversity purifies the soul

Page from a book (p. 174) with text and printer's device on the verso. In an oval cartouche, the bank of a river. On the bank stand two men beating a piece of cloth with sticks that they both hold. In the background, a man stands in the river. He also beats a piece of cloth with a stick. Another man rows past in a small boat. Above the cartouche, the title (motto) of the print and a biblical quote (Proverbs 20:9). Below the print, an inscription: 'Strike hard and fiercely; it cleans well' and a description explaining the print. To wash dirty cloths properly, they must be worked hard. Similarly, man must be treated harshly so that his soul becomes pure.
