FIRST EDITION OF GALLUCCI’S RAREST WORK, DESCRIBING AND ILLUSTRATING THE CONSTRUCTION OF HIS IMPROVED ARMILLARY SPHERE, a kind of spherical astrolabe. The instrument, which originated in ancient Greece, passed through Arab cultures to Europe in the middle ages, and was developed by Renaissance scientists such as Gallucci and Tycho Brahe. It was both a model of the heavens and, as here, a calculating instrument for determining celestial motions and positions.
Gallucci presents a step-by-step guide to the construction of his armillary sphere. Each individual part of the instrument is described in detail and illustrated. A large woodcut on folio 9 depicts the assembled sphere. The second and third parts of the book describe the instrument’s various applications. Gallucci provides a table of stars, their positions and their magnitudes for the determination of time and position.
Gallucci (1538 -1621) was a Venetian mathematician, cartographer, astronomer, and humanist. His is famous for, among other things, the first Copernican star atlas, his Theatrum mundi, published in Venice in 1588.
