      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.
