This object was probably acquired after 1914 and therefore was not part of George IV's Kunstkammer. However, it dates from the late eighteenth century and may have been used to contain an artefact like a bezoar stone. Bezoar stones, essentially a mass taken from the stomach of a ruminant animal, were traditionally thought to have miraculous anti-venomous properties and were therefore mounted for the Wunderkammer in the same way as ostrich eggs or coconuts. Many of these were mounted in Goa, often with elaborate gold filigree cages.
