This engraved print shows a celestial globe, a terrestrial globe, and an armillary sphere, each supported on a mount decorated with caryatids. The inscription refers to John Baptist Homann (1664-1724), a German engraver who established an influential cartographic house in Nuremberg in 1702. Johann Gabriel Doppelmayr, a professor of mathematics who worked with Homann on several astronomical projects, may have had a hand in the creation of this image.
