Very scarce pair of celestial maps on two separate sheets. The pair features the northern and southern skies and is derived from the planispheres in Hevelius, Firmamentum Sobiescianum. The constellations include the Southern Cross, Leo, Ursa Major, Camelopardus, Musca, Orion and many more. They are beautifully engraved with the ribbon-style titles against a densely engraved background, and a key at the lower right indicates the brightness of the stars on a scale of 1-6, indicated by size. Johann Zahn (1641-1707) was a German mathematician who is known for his creation of an advanced camera obscura, as well as early telescopes.
