Johann Gabriel Doppelmayr was an astronomer of high repute and made a specialty of lunar observations. The main focus of this chart is the comparison of synodic periods as observed from Earth and other planets, as well as observations of Mercury and Venus. Within this chart, there is a scene depicting heavenly creatures making observations through a telescope from their vantage in the clouds. Surrounding the chart are Tychonic models of Mercury and Venus and a miniature double-hemisphere map of the world.

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.
