He was involved in the measurement of the diameter of the
Earthtogether with a team of scientists under the patronage of al-Ma'mūn in Baghdad. His textbook "Elements of astronomy on the celestial motions", written about 833, was a competent descriptive summary of Ptolemy's Almagest. It was translated into Latinin the twelfth century and remained very popular in Europeuntil the time of Regiomontanus. In the seventeenth century the Dutch orientalist Jacob Goliuspublished the Arabic text on the basis of a manuscript he had acquired in the Near East, with a new Latin translation and extensive notes.
Later he moved to
Cairo, where he composed a very important treatise on the astrolabearound 856. There he also supervised the construction of the large Nilometeron the island of al-Rawda (in Old Cairo) in the year 861.
The Alfraganus crater on the
Moonwas named after him.
