Astrolabe
Model of the changing positions of the firmament in relation to the horizon. Regiomontan school, Nuremberg, fifteenth century

The sky is projected onto a circle. A pivoted disk specifies the visible horizon. Sights on the rear of the instrument serve to measure the height of a star above the horizon.
