north of the Alps; it provided a solace and retreat for contemplation that also served to demonstrate his imperial magnificence and power in symbolic arrangement of their display, ceremoniously presented to visiting diplomats and magnates. Rudolf's uncle, Ferdinand II, Archduke of Austria, also had a collection, organized by his treasurer, Leopold Heyperger, which put special emphasis on paintings of people with interesting deformities, which remains largely intact as the Chamber of Art and Curiosities at Ambras Castle in Austria. "The Kunstkammer was regarded as a microcosm or theater of the world, and a memory theater. The Kunstkammer conveyed symbolically the patron's control of the world through its indoor, microscopic reproduction." Of Charles I of England's collection, Peter Thomas states succinctly, "The Kunstkabinett itself was a form of propaganda.". 17th century Two of the most famously described seventeenth-century cabinets were those of Ole Worm, known as Olaus Wormius (1588–1654) (illustration, above right), and Athanasius Kircher (1602–1680). These seventeenth-century cabinets were filled with preserved animals, horns, tusks, skeletons, minerals, as well as other interesting man-made objects: sculptures wondrously old, wondrously fine or wondrously small; clockwork automata; ethnographic specimens from exotic locations. Often they would contain a mix of fact and fiction, including apparently mythical creatures. Worm's collection contained, for example, what he thought was a Scythian Lamb, a woolly fern thought to be a plant/sheep fabulous creature. However he was also responsible for identifying the narwhal's tusk as coming from a whale rather than a unicorn, as most owners of these believed. The specimens displayed were often collected during exploring expeditions and trading voyages. Cabinets of curiosities would often serve scientific advancement when images of their contents were published. The catalog of Worm's collection, published as the Museum Wormianum (1655), used the collection of artifacts as a starting point for Worm's speculations on philosophy, science, natural history, and more. Cabinets of curiosities were limited to those who could afford to create and maintain them. Many monarchs, in particular, developed large collections. A rather under-used example, stronger in art than other areas, was the Studiolo of Francesco I, the first Medici Grand-Duke of Tuscany. Frederick III of Denmark, who added Worm's collection to his own after Worm's death, was another such monarch. A third example is the Kunstkamera founded by Peter the Great in Saint Petersburg in 1714. Many items were bought in Amsterdam from Albertus Seba and Frederik Ruysch. The fabulous Habsburg
