The majority of these books are included in Tusi’s famed compendium Majmu’at al-Mutawwasita described by Tusi as "intermediate", lying between Euclid's Elements and Ptolemy's Almagest ('Nasir al-Din Tusi', Encyclopedia of Islam, pp.929-932). It contains a group of treatises on mathematics and astronomy of which, in most cases, he had written commentaries or new editions himself. Nasir al-Din Abu Ja'far Muhammad bin Muhammad al-Tusi was born in Tus in 1201 AD. He was the most eminent scholar of the medieval world in trigonometry and wrote on a wide range of topics within the areas of mathematics and astronomy as well as on logic and theology. He is well-known as the founder of the observatory at Maragha in 1259 AD for the Ilkhanid ruler Hülegü. He died in 1274 AD.
