The Astrology of Space - Matrix Software

The Astrology of Space
degrees of space in any direction, we must have a
plane to which all objects, stars, planets, etc. may be
referred – a reference plane. Every coordinate system
must have a plane of reference that passes through
the center of the system and which divides all space
into two equal halves or hemispheres.
We have mentioned, when speaking of the zodiac,
that it is the plane of the Earth's orbit that is used as
the fundamental reference plane for the ecliptic
system of coordinates. We may specify the position of
all objects as either above (north) or below (south) of
this plane by a number of degrees of arc that range
from 0° (the plane itself) to 90° above or below this
plane – the north and south poles of the ecliptic. We
must also choose (and this is the most arbitrary
factor) a point or direction in space (somewhere along
the plane itself) from which to measure longitude of
arc from 0° to 360°– zodiac longitude. In the tropical
ecliptic system used by most Western astrologers,
this point is the zero-degrees Aries point or Vernal
Equinox (to be explained later).
