This print is titled "Sphaera Mundi" by Johann Gabriel Doppelmayr circa 1750

A celestial chart depicting four views of equatorial, ecliptic, tropical, and polar circles among the lines of longitude and latitude. This print was not published in Doppelmayr's "Atlas Coelestis" but another atlas published by Homann Heirs. If this print was from "Atlas Coelestis" it would have the Arabic numeral 1 printed in the upper right corner. Instead, this copy has the Roman numeral XX printed at the bottom center. The print was engraved sometime between 1716 and 1724.
