These interestings leaves are from Gallucci's early, important star atlas. The atlas included numerous illustrations and diagrams such as armillary spheres and planetary orbits, and a superb selection of volvelles that 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. This lot includes a volvelle with two moveable discs, and three astronomical instrument illustrations. Gallucci's work, originally published in Latin (Theatrum Mundi, et Temporis…) in 1588, was completed only 45 years after Copernicus's 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 Spanish editions from 1606-57.
