Parallax Theory in Islamic Astronomy

  title={Parallax Theory in Islamic Astronomy},
  author={E. S. Kennedy},
  pages={33 - 53}
THIS paper is, as the title indicates, a survey of the available material on parallax theory as applied by astronomers of the Near and Middle East and Spain from the eighth through the fifteenth centuries. To the knowledge of the author, the topic has not been treated in the literature for the last fortyodd years and before that only incidentally. Nevertheless it was a subject of moment to the medieval astronomer, who had to take account of solar and lunar parallax in the computation of solar… Expand
