6 T P S .   M A T H E M A I C H - H Y S I С S A L O N THEATERPLATZ 1 Today ’ s permanent exhibition in the Zwinger shines a spotlight on objects that show how we began to understand our world : The development of the clock – from the early modern period to its production in the manufactory in Glashütte , Saxony , in the nineteenth century – is presented next to a celestial globe from the late thirteenth century , one of only five known globes from this period , created in today ’ s Iran . The calculating machine developed by the French mathematician and philosopher Blaise Pascal can be tried out by visitors as a 3D model , and elaborate digital animation allows for a glimpse of the inner life of many objects : for example , the drumming bear of 1625 , who sports real fur and a clock - face on his chest . As long as the clock ticks , the bear ’ s eyes roll back and forth . The Langgalerie , which extends from the Kronentor to the central pavilion , now houses the display on mechanical marvels and mathematical instruments from around 1600 . This part of the exhibition reveals how the collection originated in the 16th - century Kunstkammer , or ‘ chamber of the arts ,’ of the Electors of Saxony , which was housed within the Palace at their court seat in Dresden . It explores the Electors ’ intensive engagement with questions relating to measurement , surveying , and astronomy , and their enthusiasm for elaborate mechanical devices . In the newly - created exhibition space within the Zwinger ramparts an array of terrestrial and celestial globes are on display from the Salon ’ s world - famous collection . The oldest exhibit on show here is an Islamic celestial globe dating from the 13th century . For the first time , these fragile artifacts will be able to be presented completely protected from the harmful effects of daylight . The pavilion ’ s upper floor , the grand Festsaal , is dedicated to the history of the Salon within the Zwinger itself . Until 1945 this room housed the Salon ’ s entire holdings . Visitors can retrace the original idea and motives that lay behind installing a cabinet of physical instruments here in the mid - 18th century . It is here that the official local time for Dresden was determined over period of 150 years and that the first systematic meteorological measurements of the region were made .
