This geographical and astronomical chart was the first plate in this important celestial atlas. It presents four views of equatorial, ecliptic, tropical, and polar circles among the lines of longitude and latitude. Two small charts demonstrate solar positions with respect to the earth and the refraction of light. The corners are decorated with four types of globes and armillary spheres: Ptolemaic armillary sphere, Copernican armillary sphere, celestial globe, and terrestrial globe.
Johann Gabriel Doppelmayr and Johann Baptist Homann were frequent collaborators in producing celestial and astronomical charts for atlases. This chart was engraved between 1716 and 1724 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.
