After publishing the Bible, Gutenberg's next ambition was a laxative timetable known as the Purgation-Calendar. This unusual choice highlights the quirky aspects of historical publishing and reflects on the diverse subjects that were of interest at the time. The intention behind this calendar seems to emphasize practicality over the more sacred texts that preceded it.

The text also touches on the vast array of humorous and colorful German proverbs related to bodily functions. One such saying humorously suggests that just as fish dwell in water, excrement is closely associated with the human body. This illustrates not only the cultural perspective on such topics but also the rich tradition of folk sayings that often contain wisdom wrapped in humor.
