Astrolabe of ‘Umar ibn Yusuf ibn ‘Umar ibn ‘Ali ibn Rasul al-Muzaffari
New York, United States of America
The Metropolitan Museum of Art
Dated Hegira 690 / AD 1291
Brass; cast and hammered, pierced, chased, inlaid with silver
This astrolabe is unusually well documented for an object produced during the medieval period. Its inscription attributes it to a Rasulid prince, ‘Umar ibn Yusuf, a few years before he ascended to the throne (r. 1295–96). ‘Umar compiled a number of scientific treatises, including one on the construction of astrolabes, an autographed version of which is preserved in Cairo and contains certifications by his teachers as to his competence as a maker of such devices and a description of this very piece.
