It was used to demonstrate celestial phenomena and determine the time and equatorial and ecliptic coordinates. The armillary sphere enabled simulation of astronomical phenomena, including the movement of planets in relation to the Sun. It was made by Franciszek Słupski as part of his doctoral thesis defended at the Philosophy Department of the University of Kraków. **For more images and further information, visit:** https://muzea.malopolska.pl/en/objects-list/2792 Inventory number: 4307; 307/V Localisation of the physical object: Jagiellonian University Museum Collegium Maius, Kraków, Poland **Digitalisation: Regional Digitalisation Lab, Małopolska Institute of Culture in Kraków, Poland; “Virtual Museums of Małopolska” project**
