Doppelmayr is the cartographer, astronomer and mathematician. He held the post of Professor of Mathematics at the Aegidien Gymnasium, Nuremberg from 1704-1750. The prolific globe-maker, Doppelmayr produced celestial charts from 1704 onward, in his determination to explain the Copernican-Huygens world system. Homann, one of the main publishers of astronomical maps in 18th century Germany, settled in Nuremberg in 1688 and established his publishing house there. They were published as a book. Each of the copper-engraving are double pages from the original book and are printed on both sides and some are partly colored with titles and tables in green, pink and yellow wash. They are framed in a brass and glass frames in the 20th century and have blue passe-par-touts with gilded edges. The group of six engravings you see are on the 2nd photo; Astronomia comparativa Tabula Selenographica Hevelii Riccoli Theoria Satelithum Iovis et Saturni Globi Coelestis in Tabulas Planas Redacti, Pars II-III and VI from Hemisphaerium coeli. Doppelmayr developed a close relationship with the Dominican friar and cartographer Johann Batist Homann, the founder of a famous cartographic publishing firm. In the early 1700's, Doppelmayr prepared a number of astronomical plates that had appeared in Homann's atlases, which in 1742 were collected and issued as the Atlas Coelestis in quo Mundus Spectabilis\. The atlas contained 30 plates, 20 of which treated astronomical themes and historical development, including Copernicus's and Tycho Brahe's cosmological systems, illustration of planetary motion and the Solar System, and a detail of the Moon's surface based on telescopic advances. The remaining ten plates were actual star charts, including hemispheres centered on the equatorial poles.Two other plates were hemispheres centered on the ecliptic poles with an external orientation, featuring contemporary illustrations of European observatories, which Doppelmayr visited during his travels.
