Description: The inscription on the back firmly dates the object and states that "this astrolabe was the work of cUmar ibn Yusuf ibn cUmar ibn cAli ibn Rasul al-Muzaffari, directly and by dictation." This Rasulid prince later became sultan for only one year. He was interested in astronomy and mathematics and wrote a treatise containing tables for marking the curves of the astrolabe plates indicating the latitudes of the most important Yemenite cities. The object is composed of eight elements: case, alidade (rule), rete (network), four uniform plates, and a bolt or pin that keeps the parts in place. An astronomer would suspend the astrolabe by his thumb and hold it toward the starry sky when he needed to consult it .
