First edition of the most luxurious and intrinsically beautiful scientific book that has ever been produced” (D.J. de Solla Price, Science since Babylon, p. 104), in an extraordinary hand coloured copy in first issue, as attested by the repeated fol. G3 and by the letterpress cancel slip on fol. K1r, preserved in a beautiful contemporary Venetian binding.

The author of this popular texbook in astronomy is Petrus Apianus, astronomer and professor of mathematics at Ingolstadt, a veritable pioneer in the production of astronomical and geographical devices.
Apianus’ work on the project began eight years before and the Astronomicum Caesareum, which was printed in his private press at Ingolstadt, is considered the most spectacular contribution of the book-maker’s art to sixteenth-century science” (Gingerich, Apianus’s Astronomicum Caesareum, p. 168).

The handbook is divided in two parts: the first (ll. B1-M3) includes 40 chapters with maps reproducing the position and the movement of celestial bodies, while the second part describes the meteroscope, an instrument designed to solve problems in spherical trigonometry, and reletes the sighting of five comets: The Astronomicon is notable for Apian’s pioneer observations of comets (he describes the appearances and characteristics of five comets, including Hailey’s) and his statement that comets point their tails away from the sun. Also important is his imaginative use of simple mechanical devices, particularly volvelles, to provide information on the position and movement of celestial bodies” (DSB., I, p. 179). For the dissemination of calculating technology in a standardized and reproducible form, Poulle has compared the appearance of paper instruments’ to nothing less than the advent of printing (see Les instruments de la théorie des planètes, 1.83).

The present copy represents one of the most complete to have ever appeared on the market: the Horblit copy lacked 23 volvelles and one pearl, while the Honeyman copy lacked 7 volvelles, one silk thread and nine pearls.
