Notes
An astrolabe in the shape of a clock, containing seven plates, one of which is fixed and the rest rotating. The six rotating plates are connected to the fixed plate by a screw decorated with a rosette. These plates were engraved with lines of longitude, concentric circles, and terms and names related to astronomy and the stars. An indicator with hooked ends was also placed on the top surfaces of these plates, which can be used to determine the locations of 29 stars. These, in turn, can be used to measure time and distance. Historical sources indicate that the astrolabe was invented by the Greek astronomer Hipparchus in the second century BC. Muslims in Andalusia and Morocco used the most advanced types of astrolabe.
