A point equal in distance on the opposite side of the solsticial axis to a planet's position. It is effectively the "shadow" of a planet. The midpoint of a planet's position and its antiscion is always the point of the solstice (1° Cancer – 1° Capricorn). For example, when the Sun is in the tenth degree of Taurus, this is as far distant from the first degree of Cancer as it would be if placed in the twentieth degree of Leo, its Antiscion, so energising any planet in that degree or which casts an aspect to that degree. Once held to be a powerful fortitude equivalent to sextile or trine, this is rarely considered by modern astrologers, perhaps because it is a geometrical abstraction, rather than a real rock.
