AbstractFor more than one thousand years the astrolabe was one of the most used astronomical instruments in both the Islamic World and Europe. It was used to locate and predict the positions of the sun and stars, for instance to determine local time. In the first part of the workshop, the participants learn how to use (a cardboard model of) the astrolabe. In the second part they study the mathematical and astronomical principles on which the astrolabe is based. We explain the mathematical properties of the stereographic projection and we show how the lines and circles on the astrolabe can be computed.
