An interesting chart of the satellite systems of Jupiter and Saturn compared with the Earth-Moon system according to the observations of Giovanni Domenico Cassini in Bologna in 1661. Includes several descriptive tables at top and bottom. This is the fourteenth plate of thirty in the atlas.
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 example on a bright sheet with a hint of soiling and some pencil markings in the blank margins.
