This celestial globe is the 1750 reissue by Wolfgang Paul Jenig (d.1805) of the 1830 globe by Johann Gabriel Doppelmayr (1671-1750). The celestail gores of the 1730 issue were left unaltered, but the terrestrial gores were updated; Jenig would continue updating the terrestrial gores until the end of the century, taking particular interest in the voyages of discovery of Cook and others.
The celestial chart is taken from the star catalogue Prodomus Astrnomiae by Polish astronomer Johannes Hevelius (1611-1687) from Danzig (Gdansk), published posthumously in 1690. Hevelius, Dekker and Krogt note, was one of the last astronomers to conduct his investigations without a telescope, preferring instead the power of his very good eyesight to measure the positions of the stars, and arguing that these were no worse than those derived with the optically not very reliable telescopes of the day. His newly designed constellations figured on most of the celestial globes of the first half of the eighteenth century. He was also the first person, in his Selonographia of 1847, to suggest the idea of building a lunar globe (carried out by Christopher Wren, although this relief moon globe is now lost).
