A beautiful matched pair of celestial charts covering the entire night sky based on Hevelius. The northern sheet locates the non-Ptolemaic constellations of Antinous, Chioma di Berenice, Giraffa, Alicorno, Musca and the 8 northern Hevelius ones. It is surrounded by engravings of four important Italian observatories at Pisa, Padua, Milano, and Bologna. The southern sheet delineates the non-Ptolemaic constellations of Colomba, the 12 of Keyser & Houtman, Quercia di Carlo, and Scuto Sobieski. The surrounding vignettes depict important observatories at Copenhagen, Greenwich, Cassel, and Paris, each with astronomers on the roof viewing through telescopes. Both maps have a legend that gives the brightness of stars from magnitude 1 to 6. Both are drawn by G. Zuliani and engraved by G. Pitteri. A lovely set of maps not often offered together.

Nice impression on sheets with the watermark of three crescent moons. There are a few errant spots of colorist's ink.
