Maslama al-Majriti

Lived c. 950–1007 (about 57 years)

Also known as
Maslama of Madrid, Maslama al-Magriti

Maslama al-Majriti was an astronomer and mathematician of the Córdoba caliphate. His name means "of Madrid", where he was probably born around 950. He studied in Córdoba, worked there until his death, and is dated to 1007, though one Spanish source gives 1008.

He belonged to the court circle of al-Hakam II, and his contemporaries counted him the leading astronomer of his day. He is also credited with founding a school of Andalusian astronomers.

His trace in the city is intellectual rather than architectural, and it is better to say so than to send you hunting for a plaque. No building in Córdoba can be tied to him with confidence. What you can do is read the world he worked in. The caliph whose reign overlapped his career is the subject of Al-Hakam II and the library of 400,000 books that vanished. For another Córdoba scientist whose reputation outran the evidence, see Ibn Firnas and the flight legend, and for a contemporary of the same court, Al-Zahrawi, the Córdoba surgeon.

His career, his tables and the books wrongly attached to his name are told in Maslama al-Majriti: The Astronomer Who Reset Córdoba's Sky. Read the full story there.
