Ibn al‐Bannāʾ al‐Marrākushī al-Azdi, also known as Abu'l-Abbas Ahmad ibn Muhammad ibn Uthman al-Azdi ({{lang-ar|ابن البنّاء}})

(29 December 1256 – c. 1321), was a Moroccan-berber[1] mathematician, astronomer, Islamic scholar, Sufi, and a one-time astrologer.

Biography

Ibn al-Banna' (lit. the son of the architect) was born in Marrakesh in 1256; he is named al‐Marrākushī after that city.[2] Having learned basic mathematical and geometrical skills, he translated Euclid's Elements into Arabic.[2][3][4][5][6]

Works

Ibn al-Banna' wrote between 51 and 74 treatises, encompassing such varied topics as Algebra, Astronomy, Linguistics, Rhetoric, and Logic. One of his works, called Talkhīṣ ʿamal al-ḥisāb ({{lang-ar|تلخيص أعمال الحساب}}) (Summary of arithmetical operations), includes topics such as fractions, sums of squares and cubes etc. Another, called Tanbīh al-Albāb,[7] covers topics related to:

  • calculations regarding the drop in irrigation canal levels,
  • arithmetical explanation of the Muslim laws of inheritance
  • determination of the hour of the Asr prayer,
  • explanation of frauds linked to instruments of measurement,
  • enumeration of delayed prayers which have to be said in a precise order, and
  • calculation of legal tax in the case of a delayed payment

He also wrote Rafʿ al-Ḥijāb (Lifting the Veil) which covered topics such as computing square roots of a number and the theory of continued fractions.[2] This was the first mathematical work since Brahmagupta to use an algebraic notation, further developed by Abū al-Hasan ibn Alī al-Qalasādī two centuries later.[8]

Legacy

The crater Al-Marrakushi on the Moon is named after him.
