"Astronomia Comparativa…", Doppelmayr/Homann

Johann Gabriel Doppelmayr was an astronomer of high repute and made a specialty of lunar observations. This interesting chart centers on a large sphere showing positions of the sun, moon, Venus and Mercury and engraved with a scene of Diana (lady of the moon) observing the earth through a telescope. In each corner is a diagram: Mercury, Venus, phases of the moon, and an interesting double hemisphere showing the earth as seen from the moon. In the Western Hemisphere, California appears as an Island. The map is typical of the detailed and bold style of the Homann cartographic output, of which the celestial maps are amongst the most attractive.
