Inside the Kunstkammer: the circulation of optical knowledge and instruments at the Dresden Court

The Kunstkammer of the Electors of Saxony, founded in Dresden around 1560, housed one of the richest collections of tools and scientific instruments in its day. A close analysis of the optical objects in the collection in the decades around 1600 is undertaken here—in particular, their arrangement by a mathematically trained curator, Lucas Brunn, and their use in an ‘experiment’ by a distinguished visitor, Johannes Kepler. It is argued that the selection, display and use of optical objects within this collection reflect a specific, playful image of optics promoted at the Saxon court.
