This celestial chart shows the irregular orbits of Mercury and Venus on Tycho Brahe’s model, as observed from Earth, for the years 1712 and 1713. The allegorical scene represents the planets themselves, being pushed on their celestial swings.
Doppelmayr became professor of mathematics at the Aegidien-Gymnasium in Nuremberg in 1704, and enjoyed a close working relationship with the founder of the Homann firm, Johann Baptist Homann. Astronomical plates prepared by Doppelmayr appeared in early editions of Homann’s general atlases before being collected together and published as the ‘Atlas Coelestis’ by the Homann Heirs in 1742.
