The astrolabe is in the form of a clock face. Seven plates belong to it, one of them fixed and the others rotating. The six rotating plates are attached to the fixed one by a central screw decorated with a rosette. On top of the faces of these plates, which have meridians, concentric circles and astronomical and astrological terms and names engraved on them, is placed an indicator with hooked ends which can be used to determine the positions 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. The most advanced types of astrolabe were used by the Muslims of al-Andalus and the Maghreb.
