Astrolabe
Description
Astrolabe made of brass pertaining to the Ottoman era. It consists of a round body which ends at the top in a pointed shape with a ring (armilla) to hang the instrument, called the "throne" (al Kursi).
The edge of the disk (limb) is marked in degrees and the frame includes numbers pertaining to astronomy. Astrolabe is originally a Greek word, which literally meant "to take the star" or star mirror.
The astrolabe is a precise astronomical instrument to measure the location of the sun, planets and some stars in the hemisphere. It measures angles, shape, size and height as well as the course of celestial objects around the celestial pole.
The top part of the astrolabe shows round and flat discs made of brass with a metal pointer. These discs are embossed with the names of the houses in the zodiac and stars.
