Abu I-Abbas Ahmed al-Farghani, also known as Alfraganus in the West, was an astronomer in the Abbasid court in Baghdad,
and one of the most famous astronomers in the 9th century.
Farghani composed several works on astronomy and astronomical equipment
that were widely distributed in Arabic and Latin and were influential to many scientists.
His best known work, whose name translates to Elements of astronomy on the celestial motions,
was an extensive summary of Ptolemy's Almagest containing revised experimental data.
