See Astronomy, vol. i. p. 325, &c. The equinoElial 
;points , are the two oppolite points where the ecliptic and 
equinoctial crofs each other; the one point being in the 
beginning of Aries, and called the vernal point, or ver¬ 
nal equinox ; and the other in the beginning of Libra, 
and called the autumnal point, or autumnal equinox. 
It is found by obfervation, that the equinoCtial points, 
and all the other points of the ecliptic, are continually 
moving backwards, or in antecedentia, i. e. wellwards. 
This retrograde motion of the equinoctial points, is that 
phenomenon called the Precellion of the Equinoxes. See 
Astronomy, p. 372.
