Northern and Southern Celestial Map, 1795.
Historical map of the sky of the northern and southern hemisphere, showing the stars and mythological drawings of the constellations. This map is centred on the geographic north and south pole, with the plane of the ecliptic (arching through lower and upper centre) showing the constellations of the northern and southern zodiac. The zodiac shows the Sun’s passage through the sky throughout the year, and does not align to the geographic equator because the Earth is tilted on its axis. The relative brightness of the stars is shown, as well as the Milky Way.
