名詞

zij (plural zijes)

1. (Islam) An Islamic book that tabulates parameters used for various astronomical events and movements.
   • 2003, José Chabás, Bernard R. Goldstein, “Astronomical Commentary”, in The Alfonsine Tables of Toledo:

     Zijes are comprised of a set of canons and a set of tables. These tables can be grouped as follows: calendar conversions; mean motions; solar, lunar, and planetary equations; trigonometry and spherical astronomy; planetary latitudes, visibilities, and retrogradations; lunar visibility; precession or trepidation; solar and lunar eclipses; astrological tables; geographical coordinates; and star lists. Some zijes may not have had all these items, and others may have had [more]. In particular, planetary velocity tables appear in only [those] that derive from the Iberian Peninsula and the Maghrib.
