Biography

Ibn al-Banna' (lit. the son of an architect) was born in Marrakesh in 1256.[1] Having learned basic mathematical and geometrical skills he proceeded to translate Euclid's Elements into Arabic.[1]

Works

Ibn al-Banna' wrote between 51 to 74 treatises, encompassing such varied topics as Algebra, Astronomy, Linguistics, Rhetoric, and Logic. One of his works, called Talkhīṣ ʿamal al-ḥisāb (Arabic, تلخيص عمل الحساب ) (Summary of arithmetical operations), includes topics such as fractions, sums of squares and cubes etc. Another, called Tanbīh al-Albāb,[2] 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

Yet another work by Ibn al-Banna' was Rafʿ al-Ḥijāb (Lifting the Veil) which included topics such as computing square roots of a number and theory of continued fractions.[1] This work was also the first mathematical work since Brahmagupta to use an algebraic notation, which was then further developed by his successor Abū al-Hasan ibn Alī al-Qalasādī two centuries later.[3]
