This is a fascinating and fully functional volvelle. Galluci included fifty-one different volvelles in the Theatro del Mundo. These were used to solve problems concerning the calendar, tide tables, the rising and setting of the sun, moon, or stars, and the positions of planets. Because of their delicate nature most volvelles have not survived intact.
