## Summary

A silver-and-gilt-brass globe engraved with the constellations, carried on the back of a large silver figure of the winged horse Pegasus, with a clockwork movement inside that once turned the sphere and moved a small gilt sun along its engraved ecliptic. Made in Vienna in 1579 by Gerhard Emmoser, Imperial Clockmaker to the Habsburg court, it is identified in the 1607-1611 inventory of Emperor Rudolf II's Prague Kunstkammer, one of the greatest princely collections of scientific instruments and automata ever assembled.After that its trail goes dark for well over a century. It resurfaces in Stockholm in the collection of the exiled Queen Christina of Sweden by 1652, almost certainly among the plunder Swedish troops carried out of Prague Castle in 1648, then vanishes again until a Paris estate sale in 1770 and a repair inscription of 1781. How it crossed the following 136 years to reach J. Pierpont Morgan, who gave it to the Metropolitan Museum in 1917, is not recorded in any source consulted here.What survives is a working demonstration of how a Renaissance court fused astronomy with princely display: a scientific instrument built to the accuracy of a working clock and the splendor of a goldsmith's masterpiece, mounted on a mythological beast chosen, the Museum's own curators argue, because Pegasus stood for the wings of the human mind lifting the science of astronomy.

## Provenance

Every link carries a grade. `documented` means a cited source supports it, `disputed` means the identification is argued but not established, `unknown` means we have no owner for that span and have not bridged it.

- **1579** Made by Gerhard Emmoser, Imperial Clockmaker, Vienna `[documented]` (origin)
  Dated 1579 by the Metropolitan Museum's own cataloguing, three years into Rudolf II's reign. No commission record survives naming an original patron.
- **1579-1607** Unknown `[unknown]` (gap)
  No owner or location is documented between the globe's manufacture and its identification in Rudolf II's Kunstkammer inventory.
- **1607-1611** Holy Roman Emperor Rudolf II, Prague Kunstkammer `[documented]` (inventory)
  Identified from a description in the Kunstkammer inventory compiled by imperial antiquarian Daniel Froeschl between 1607 and 1611; the manuscript survives in the Princely Library of Liechtenstein, Vaduz.
- **1611-1652** Unknown `[unknown]` (gap)
  No specific document for this object bridges the inventory of 1607-1611 and Queen Christina's recorded ownership by 1652, though the 1648 Swedish sack of Prague Castle is well documented as the general mechanism by which much of Rudolf II's Kunstkammer reached Sweden.
- **by 1652-1654** Queen Christina of Sweden `[documented]` (ownership)
  Recorded in the Metropolitan Museum's own catalogue note as in Christina's collection by 1652, two years before her abdication.
- **1654-1770** Unknown `[unknown]` (gap)
  No owner, dealer or location is documented across the roughly 116 years between Christina's abdication and the globe's reappearance in Paris.
- **1770** Avocat Fortier, conseiller du roi `[documented]` (sale)
  The globe reappeared on 20 April 1770 at the Paris sale of the collection of Avocat Fortier. No sale price is recorded in the sources consulted.
- **1770-1781** Unknown (in Paris) `[documented]` (repair)
  An inscription inside the globe dated 15 May 1781 records a repair by the Paris clockmaker Gautrin, probably Pierre-Laurent Gautrin (d. 1823), establishing the globe was in Paris at that date even though the owner who commissioned the repair is not named.
- **1781-1917** Unknown `[unknown]` (gap)
  No dealer or collector is identified between the 1781 repair and J. Pierpont Morgan's ownership, a gap of roughly 136 years.
- **by 1913-1917** J. Pierpont Morgan estate `[documented]` (bequest)
  Morgan died in 1913; the gift to the Metropolitan Museum was completed in 1917, as part of a large group of European clocks and watches from his collection carrying consecutive accession numbers in the 17.190 series.
- **1917-present** Metropolitan Museum of Art, New York `[documented]` (acquisition)
  Accession 17.190.636, Department of European Sculpture and Decorative Arts, credited Gift of J. Pierpont Morgan, 1917. Shown in "The Luxury of Time" (2015-16) and "Making Marvels" (2019-20).

## Open questions

- Who first commissioned or received the 1579 globe? No contract, payment or correspondence naming an original patron has surfaced; its documented history begins only with its identification in Rudolf II's own Kunstkammer inventory of 1607-1611.
- Does the clockwork still function, or has it been arrested for conservation? The Museum's own text says the globe 'originally rotated', in the past tense, but no source consulted for this record states its present mechanical condition directly.
- Where was the globe between about 1652, when it is recorded in Queen Christina of Sweden's collection, and 20 April 1770, when it reappeared at the Avocat Fortier sale in Paris? No owner is documented across that roughly 118-year gap.
- Who owned the globe between the Gautrin repair inscription of 15 May 1781 and J. Pierpont Morgan's acquisition of it before his death in 1913? No dealer or intermediate collector is identified in any source consulted for this record.
- What exactly does the subsidiary dial mounted on the horizon-ring arm display? Secondary summaries of the Museum's catalogue describe separate hour and calendar functions, but this could not be verified against the Museum's own full catalogue text during research for this record.
- When and where was Gerhard Emmoser born? Only his active career, from 1556 to his death in 1584, is documented in the sources consulted; a single unverified secondary source gives Heidelberg, which this record has not been able to confirm.
