Ṣūfī spent his life in close relation to the regional rulers of the Buyid dynasty. His astronomical work, Kitāb Ṣuwar al-Kawākib (Book on the Constellations), ca 964, became very influential both in the Orient and in Europe. Its text and nomenclature influenced the encyclopedist Qazwīnī (d. 1283) and the Timurid Ulugh Beg in the star catalogue of his zīj(epoch: 1437).  For centuries, Arabic-Islamic astronomers followed the forms of the constellation figures as drawn in Ṣūfī’s book, in written works and on instruments (celestial globes). Ṣūfī’s name (= Azophi, in Latin) was given by J. B. Riccioli (1651) to one of the craters on the Moon. [Kunitzsch]
