This Brass Astrolabe, made by Muhammad Muqim during the reign of Jahangir (1605-1627) as it is inscribed, is a portable pocket-size device. Astrolabes have various applications ranging from the astrological, the astronomical, and the religious to seasonal and daily timekeeping and tide tables.

The production of astrolabes and celestial globes in the Indian subcontinent was dominated by Ustad Allah Dad and his descendants in the second half of the sixteenth century and the seventeenth century. Their astrolabes display a fine combination of geometrical precision, a high level of metal craft, and aesthetic beauty. Allah Dad's descendants revolutionized the production of the celestial globes by casting them as single hollow spheres by the lost-wax process. About a hundred and twenty astrolabes and twenty-five globes made by this family are extant today in museums and private collections in India, the Middle East, Europe, and the USA.
