This is a fascinating and fully functional volvelle, 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 is marked with signs of the Zodiac, and rotates around the circle. An extremely interesting apparatus, more amazing for the fact that is still fully functional. Because of their delicate nature most volvelles have not survived intact. Gallucci's work, originally published in Latin (Theatrum Mundi, et Temporis…) in 1588, was completed only 45 years after Copernicus' landmark astronomical work. It is notable for being the first star atlas to use a complete coordinate system. The atlas was very popular and went through numerous printings including the Spanish editions from 1606-57 that were printed in Granada. Galluci included 51 different volvelles in this important early star atlas.
