RICCIOLI, Giambattista (1598-1671). Astronomiae reformatae tomi duo. Bologna: Heirs of Vittorio Benatio, 1665.

2o (363 x 235 mm). Title page printed in red and black with engraved arms of Ferdinand Maria, Prince Elector of Bavaria, 2 engraved folding plates by Domenico Fontana after Francisco Maria Grimaldi (previously used in the Almagestum novum) and numerous woodcut illustrations in text. Contemporary vellum, spine ink lettered (light splitting to upper joint).

FIRST EDITION. Intended as a third and supplementary part of the Almagestum novum, the work conists of a series of individual tratises on the different bodies of the solar system and the fixed stars. Riccioli "noted the colored bands parallel to the equator of Jupiter and made observations of Satrn that, if he had had better instruments, might have led him to recignize its rings" (DSB). Although he knew of Huygens' Systema saturnia (1659, see lot 542), he disagreed with Huygens' ring theory. Houzeau & Lancaster 9230; Wellcome IV, p. 519; Norman 1827.
