Bicorporeal signs are signs of the zodiac said to be “double bodied”: Gemini, Sagittar-
ius, and Pisces. As originally used by Ptolemy, bicorporeal referred to all of the muta-
ble signs, which are the three signs mentioned above plus Virgo.BIQUINTILE
A biquintile is a minor aspect of 144°, created by subdividing a circle (360°) into five
parts. As the name indicates, a biquintile is equivalent to two quintiles (72° aspects).
The great astronomer Johannes Kepler devised quintiles and biquintiles for his astro-
logical work. Under-researched, a biquintile’s influence is sometimes said to be similar
to that of a quintile, and it is given an orb of influence of 1° to 2°.BIRTHCONTROL, ASTROLOGICAL
While the expression “astrological birth control” could have several referents, it is
usually taken to refer to the system discovered and elaborated by the Czech psychia-
trist Eugen Jonas. His initial discoveries were summed up by his three fundamental
rules—conception, determination of sex, and life capability of the fetus—which he
first formulated on August 15, 1956, according to Sheila Ostrander and Lynn
Schroeder’s book Astrological Birth Control:- The time of fertility [a second period of fertility, independent of the ovula-
tion cycle] occurs during the same phase of the moon as that in which the
woman was born. - The sex of the future child will be determined by the position of the moon
during the time of the woman’s fertility—whether the moon is found in the
positive or in the negative field [i.e., in a positive, masculine sign or in a
negative, feminine sign] of the ecliptic (or zodiac). - Unfavorable distribution of gravitational forces of the nearer celestial bod-
ies at the time of conception produces complications during pregnancy, par-
ticularly for the fetus.
These discoveries became the basis for an astrological birth control clinic that,
after overcoming much resistance, Jonas was able to establish in Czechoslovakia.
The first rule became the basis for a system of birth control that is basically an
elaboration and development of the old rhythm method. Rather than abstaining only
during the period of a woman’s ovulation, a couple also abstains on (and for several
days prior to) the day that the Sun and Moon repeat the exact angle they made with
each other at the moment of the woman’s birth. For instance, a woman born at the
exact moment of the full moon (when, with Earth as the vertex, the Sun and Moon
make a 180° angle to each other) would abstain during, and for several days prior to,
the full moon. When combined with abstention during ovulation, this modified
