Below is the universal Capuchin card dial that Jan Kragten 1) designed in 1992. Jan playfully adjusted the limits of the hour lines, as a result of which the dial looks like a children’s sailboat made out of a wooden shoe, and so this card dial is known as the sailing wooden shoe.
At the time, we thought that this was the first universal Capuchin card dial ever made. We should abandon this idea now..
Nicola Severino of Italy found two images of the universal Capuchin card dial in old literature.
This one is from a book by George Hartmann, 1535. It shows the same pattern, although mirrored.
The last image, also mirrored with respect to the card dial by Jan, is from a book by Andrea Schöner, 1562.
