Galluci included fifty-one different volvelles in the Theatro del Mundo. Volvelles 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. There is an engraved circle with 31 divisions, into which a separate piece of paper is attached with a red satin ribbon. This inner piece, with a decorative rose-like center, is marked with twelve months, and rotates around the circle. An extremely interesting apparatus, more amazing for the fact that is still fully functional.
