Al-ʻIjliyyah bint al-ʻIjliyy (Arabic:العجلية بنت العجلي)[1] was a 10th-century maker ofastrolabes active inAleppo, in what is now northernSyria.[2][3]
She is sometimes known in modern popular literature asMariam al-Asṭurlābiyya (Arabic:مريم الأسطرلابية) but her supposed first name 'Mariam' is not mentioned in the only known source about her life.
According toibn al-Nadim, she was the daughter of another astrolabe maker known as al-ʻIjliyy;[3] she and her father were apprentices (tilmīthah) of an astrolabe maker from Baghdad,Nasṭūlus.[3]
Al-ʻIjliyyah manufacturedastrolabes, an astronomical instrument, during the 10th century;[1][4] she was employed by the first Emir of Aleppo,Sayf al-Dawla, who reigned from 944 to 967.[3][1]
Beyond that information, nothing is known about her. Her supposed name, "Mariam", is not supported by sources from her time, and the phrase "al-Asturlabiyy" in the names by which she and her father are known simply means "the astrolabist", and indicates their profession; astrolabes were long known by her time.
The main-belt asteroid7060 Al-ʻIjliya, discovered byHenry E. Holt atPalomar Observatory in 1990, was named in her honor.[2] The naming citation was published on 14 November 2016 (M.P.C. 102252).[5]
She inspired a character in the 2015 award-winning bookBinti andNetflix seriesVikings: Valhalla.[6][7] She was named an extraordinary woman from theIslamic Golden Age by 1001 Inventions.[8]
