The Horizon System
We will return to some additional ideas as to the
relationship between the equator and the ecliptic after
we introduce the third major astrological system of
coordinates, that of the Horizon.
The Horizon system of coordinates represents the
third and last of the spherical systems used in
constructing a natal chart. In this system, the
reference plane is one through the birthplace or
observing point that is parallel to the horizon. The
poles of this system are the Zenith (point overhead)
and Nadir (point underfoot). The latitude-type
coordinate in this system is called Altitude and is
measured from 0° to 90° from the plane of the horizon
to either pole. The longitude coordinate is called
Azimuth and is measured from 0° to 360° along the
horizon (for astrological use in this book), starting
from the East point and moving in a counterclockwise
