Miriam al-Asturlabi

Mariam al-Asturlabiyy;

(Arabic: مريم الأسطرلابي‎ or al-ʻIjliyyah bint al-ʻIjliyy al-Asturlabiyy (Arabic: العجلية بنت العجلي الأسطرلابي‎), was a 10th-century female astronomer and maker of astrolabes in Aleppo, in what is now northern Syria. She was the daughter of an astrolabist known as al-ʻIjliyy al-Asturlabī. According to ibn al-Nadim, she was an apprentice (tilmīthah) of Muḥammad ibn ʻAbd Allāh Nasṭūlus. Al-‘Ijliyah developed and manufactured astrolabes, an astronomical and navigation instrument, during the 10th century. She was employed by the Emir of Aleppo, Sayf al-Dawla, who reigned from 944 to 967 AD.

The main-belt asteroid 7060 Al-‘Ijliya, discovered by Henry E. Holt at Palomar Observatory in 1990, was named in her honor. Naming citation was published on 14 November 2016 (M.P.C. 102252).
