The first object which you can see in the second floor of the Pergamon Museum in Berlin is this Iraqi astrolabe made by the astronomer and poet Hibât Allâh al-Bagdâdî and designed by the great Abû Jacfâr al-Khâzin (c.900-c.970). This bronze piece is unique!
Al-Khâzin was a very important Persian mathematician and astronomer who worked in Ray and wrote a Commentary on the Almagest. He also wrote one of the most important work on the construction of astrolabes which was very appreciated by his colleagues.
