The thirty plates include twenty that illustrate: the cosmographical theories of Copernicus, Tycho Brahe; planetary motions, the solar system, the moon’s surface, the theory of eclipses, the passage of comets across both the northern and southern skies. The remaining ten plates are star charts: two centered on the equatorial poles; two on ecliptic poles; and six plates that use a gnomonic projection with geocentric orientation in sequence, starting with the north equatorial pole, the vernal equinox, the summer solstice, the autumnal equinox, the winter solstice, and the south equatorial pole, all showing the paths of important comets.
“Besides being a star chart and a selenographic map, the Atlas includes diagrams illustrating the planetary systems of Copernicus, Tycho, and Riccioli; the elliptic theories of Kepler, Boulliau, Seth Ward, and Mercator; the lunar theories of Tycho, Horrocks, and Newton; and Halley’s cometary theory” (DSB)
Johann Doppelmayr (1677–1750) was “a Professor of Mathematics at the Aegidien Gymnasium in Nuremberg. He wrote on a number of topics, including astronomy, geography, cartography, spherical trigonometry, and scientific instruments, and he collaborated in the production of terrestrial and celestial globes. He was a member of the Royal Society of London and the Berlin and St. Petersburg Academies of Sciences” (Kanas). He was born in Nuremberg, the son of the merchant Johann Siegmund Doppelmayr. He entered the Aegidien-Gymnasium in Nuremberg in 1689, then the University of Altdorf in 1696. His studies included mathematics, physics, and jurisprudence. Later he continued his studies in Halle and graduated in 1698 with a dissertation on the Sun. During studying at the University of Halle, he also learned French and Italian. After giving up his legal studies he then spent two years traveling and studying in Germany, Holland, and England, spending time at Utrecht, Leiden, Oxford, and London, during which time he learned to speak French, Italian, and English. He continued to study astronomy and learned to grind and figure his own telescope lenses.
His career was academic, and he became Professor of Mathematics at the Aegidien-Gymnasium from 1704 until his death. He is not noted for any discoveries, but he did publish several works of a scientific nature. His publications covered topics on mathematics and astronomy, including sundials, spherical trigonometry, and celestial maps and globes. One of his works also included useful biographical information on several hundred mathematicians and instrument makers of Nuremberg.
