Wolfgang Paul Jenig (d.1805) was a Nuremburg publisher and pencil-maker who, in the 1790's, gained possession of the copper plates of the late Johann Gabriel Doppelmayr (1671-1750). One of the most prolific Nuremburg globe-makers of his time, Doppelmayr's globes were popular and sold well throughout the eighteenth century, and were updated and reissued in not insignificant numbers by Jenig.
What was apparently an original Doppelmayr armillary sphere was sold in these rooms on 25 November 1998; although unsigned, the style of mounting, and particularly the engraved paper horizon circle are unmistakably the work of Doppelmayr. At that time, however, no Doppelmayr armillary sphere was recorded. The appearance of this sphere, however, both bolsters the provenance of the earlier one, and marks the first time that a Jenig-reissue has been recorded. Here again the horizon paper is unmistakably that of Doppelmayr, and was doubtless printed from the original copper plates. However, in comparison with the 1998 sphere we can see the changes that Jenig made to the design of the armillary itself: no globe in the centre, but a smaller brass ball; and the addition of a wide and distinctively engraved ecliptic band.
