This great astronomical chart portrays the motions of the planets according to the Copernican theory of the solar system. The inset at the bottom shows the scale of the solar system compared with the Hugenian estimate of the distance between the Sun and Sirius. The female representation of Terra Mater is depicted, surrounded by putti representing the stars.
Johann Gabriel Doppelmayr was a professor of mathematics at the Aegidien Gymnasium in Nuremberg. Doppelmayr and Johann Baptist Homann were frequent collaborators in producing celestial and astronomical charts for atlases. This chart was engraved between 1735 and 1742 and appeared in the two major compilations of Dopplemayr’s works published by Homann Heirs; Atlas Coelestis in quo Mundus Spectabilis... in 1742, and the revised edition Atlas Novus Coelestis... in 1748.

A nice impression with full contemporary color on a sheet with a small coat of arms watermark and light soiling. The bottom margin was trimmed by the bookbinder with minor loss of the neatline, and has been extended a bit to accommodate framing.
