Women in STEM advent calendar: Day 14 – Al-‘Ijliyah al-Asturlabi

This winter, we are celebrating the festive season by honouring 25 amazing women in STEM, some of which you might not know of!

Al-‘Ijliyah al-Asturlabi

Maker of astrolabes
Mid-10th Century CE

Al-‘Ijliyah al-Asturlabi made astrolabes, learning first from her father before being apprenticed to mastercraftsman Muḥammad ibn ʿAbd Allāh Nasṭūlus. Her intricate and innovative designs led her to work for Sayf al-Dawla, the Emir of Aleppo, from 944 to 967 CE. She also inspired the titular character in Nnedi Okorafor’s sci-fi novella Binti.

Al-‘Ijliyah al-Asturlabi is also called Mariam al-Asturlabi, Mariam ‘Al-Astrolabiya’ Al-Ijliya, and Al-‘Ijliyah bint al-‘Ijli al-Asturlabi, or in Arabic, العجلية بنت العجلي الأسطرلابي .
