For an object produced during the medieval period, this astrolabe is unusually well documented. 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, preserved in Cairo, contains certifications by his teachers as to his competence as a maker of such devices and a description of this very piece.
Signature: Made and signed by the Rasulid prince al-Ashraf `Umar ibn Yusuf, later Sultan of Yemen (r.1295-96).
Inscription: Inscription in Arabic in naskhi script on back of case:
هذا الاصطرلاب عمل عمر بن یوسف بن عمر بن علي بن رسول المظفري مُباشرةً وإملاً سنة ح ٦٩
This astrolabe is the work of ‘Umar ibn Yusuf ibn
‘Umar ibn ‘Ali ibn Rasul al-Muzaffari directly [by himself]
and by his instruction in the year A.H. 690 [1291 A.D.]
