Fr.: Canon des éclipses  

Canon of Eclipses. The most famous catalogue of solar and lunar eclipses. Published in 1887 by Theodor von Oppolzer, the catalogue contains the elements of all solar and lunar eclipses between 1208 BC and 2161 AD. It has been superseded by the calculations of F. Espenak and J. Meeus, Five Millennium Canon of Solar Eclipses: -1999 to +3000 (NASA/TP-2006-214141) and Five Millennium Canon of Lunar Eclipses: -1999 to +3000 (NASA/TP-2009-214172).

Etymology (EN): Canon, from L. canon, from Gk. kanon “a straight rod, a measuring rod, rule;” Ger. Finsternisse, plural from finsternis “eclipse; darkness,” from finster “dark,” M.H.G. vinster, O.H.G. finstar “dark” + -nis suffix forming abstract nouns, → -ness.

Etymology (PE): Fehrest “index, catalogue, canon,” → index; gerefthâ plural of gereft, → eclipse.
