  Antiscion

  As modernly used in the so-called Uranian Astrology, it is the reflex position of a planet's birth position, in that degree on the opposite side of the Cancer-Capricorn axis, of which either 0º Cancer or 0º Capricorn is the midpoint. For example, the antiscion of a planet at 14º Capricorn is at 16º Sagittarius, which point becomes effective when occupied by another planet, or one in transit or by direction. As first used by Ptolemy the term is applied to two planets which have the same declination on the same side of the equator. One in the same declination on the opposite side was termed a contra antiscion. v. Parallel.
