Fátima de Madrid

Fátima de Madrid is the name given to an Arab Muslim astronomer and mathematician who supposedly lived during the late 10th and early 11th centuries in Islamic Spain. She was purportedly the daughter of the astronomer Maslama al-Majriti, with whom she is said to have worked on several astronomical and mathematical treatises, including the astronomical tables of Muhammad ibn Musa al-Khwarizmi. The earliest known account of her is the 1924 edition of the Enciclopedia Espasa-Calpe, and historians have cast doubt on whether she actually existed.

Purported career Fátima de Madrid is said to have lived in Córdoba, under the Caliphate of Córdoba, during the late 10th and early 11th centuries. She is said to have been the daughter of the famous Islamic astronomer and scientist Maslama al-Majriti. Arabist, historian, and biographer of Al-Andalus Manuela Marín similarly holds that Fátima is a historical invention from the Espasa-Calpe. Marín attributes continued discussion about her, such as on the internet and with her inclusion in a 2009 calendar titled "Astronomers who made history", to uncritical repetition of the Espasa-Calpe's content.
