All you want to know about Al-Nayrizi

Abū’l-‘Abbās al-Faḍl ibn Ḥātim al-Nairīzī (أبو العباس الفضل بن حاتم النيريزي Latin name: Anaritius), was a 9th-10th century Persian mathematician and astronomer from Nayriz, a town near Shiraz, Fars, Iran.

He flourished under al-Mu'tadid, Caliph from 892 to 902, and compiled astronomical tables, writing a book for al-Mu'tadid on atmospheric phenomena.

Nayrizi wrote commentaries on Ptolemy and Euclid. The latter were translated by Gerard of Cremona. Nairizi used the so-called umbra (versa), the equivalent to the tangent, as a genuine trigonometric line (but he was anticipated in this by al-Marwazi).

He wrote a treatise on the spherical astrolabe, which is very elaborate and seems to be the best Arabic work on the subject. It is divided into four books:

  1. Historical and critical introduction.
  2. Description of the spherical astrolabe; its superiority over plane astrolabes and all other astronomical instruments.
  3. Applications.
  4. Applications.

Ibn al-Nadim mentions Nayrizi as a distinguished astronomer with Eight works by him listed in his book al-Fihrist.
