Description

This unsigned bras astrolabe is thought to originate from the region of Andalusia in Moorish Spain. An astrolabe is in esence a model of the universe that an astronomer could hold in their hands. From its origins in the Ancient World, Islamic astronomers developed the astrolabe and its use spread. Popular in Medieval and Renaisance Europe, its many uses included timekeeping, astrology and surveying. It offers a two-dimensional depiction of the heavens, whose layout is achieved using the mathematical technique of stereographic projection. This front view shows the moveable fretwork plate called the 'rete', which denotes the positions of the stars by short straight pointers.
