Aries

Aries, the Ram, one of the signs of the zodiac, including the first 30 degrees of the ecliptic measured from the vernal equinox, or that point where the vernal passage of the sun across the equator takes place. The vernal equinox, or, as it is also called, the first point of Aries, is constantly changing its position among the fixed stars, in consequence of the Precession (q.v.) of the equinoxes. Hence the sign Aries no longer corresponds with the constellation Aries, which was the case about two thousand years ago. The present sign Aries is in the constellation Pisces, about 30° west of the original sign. See ZODIAC.
