Johann Dopplemayer was a professor of mathematics in Nuremberg. Johann Baptist Homann, a former monk who became a map engraver, produced Doppelmayer's celestial maps. They were included in the Atlas Coelestis as well as other atlases published by Homann.

1) Ephemerides Motuum Coelestium Geometricae... is a great astronomical chart that 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 is depicted surrounded by putti representing the stars.
2) Phaenomena Motuum Irregularium quos Planetae Inferiores Venus et Mercurius... is an interesting celestial chart showing the irregular motions of Earth, Mercury and Venus per the Copernican model during the year 1710. Along the left and right edges of the sheet are linear charts depicting the transit of Mercury across the Sun on November 5, 1710 and the (predicted) transit of Venus across the Sun on June 6, 1761. In the center is a circular chart of the solar system with pinwheel lines radiating out to chart Venus and Mercury's locations for particular dates in 1710. Inside the chart is an elaborate allegorical scene of the planets orbiting the sun with Terra (Earth) being pulled through the heavens in a chariot, the wheel of which is a small map of the South Pole.
3) Systema Solare et Planetarium... is a superb celestial chart showing the motion of the planets based on the Copernican model with its dimensions according to the Cosmotheoros of Christiaan Huygens. Allegorical zodiac figures encircle the diagram, which is then surrounded by richly engraved scenes of the sun, stars, planets, putti and astronomical instruments. At bottom left is a solar eclipse projected onto a terrestrial map on a polar projection that includes the island of California. Opposite is a beautiful engraving showing the comparison of the Copernican and Brahe models of the solar system and a lunar eclipse observed May 12, 1706.
