Page 2 - Three New Tables for an Astrology of Three Dimensions

Although flat horoscopes will probably remain the rule, their
portrayal of geometrical facts can be improved upon by using data
1
from the tables in this book. Illustrations in the accompanying text
indicate some of the ways in which a two-dimensional diagram can be
supplemented to the point of providing a clear picture of three-
dimensional space.
The text will be easier to follow if certain basic concepts are first
understood. They are: the poles and great circles of a sphere; sensible
(or visible) and rational horizons; terrestrial longitude and latitude;
local, sidereal and Greenwich Mean Time; and the relationship of the
inclination of the ecliptic to the equator, the Tropics, and the Arctic
and Antarctic Circles.

Spherical Coordinates and the Horoscope

A position on the surface of the earth expressed in degrees of
latitude and longitude is based on a system of spherical coordinates
herein referred to as “axial.” The poles of this system are on the axis of
rotation. Measurements are made from the point where a particular
line of longitude (the Prime Meridian) intersects the great circle
perpendicular to it (the equator), equidistant from the poles.

P is at the intersection of the Prime Meridian and the equator

1 Three New Tables was produced as a book in 1973. The bulk of the effort was in
writing Fortran IV programs to create the tables; the latter occupied 240 pages of
that volume. Personal computers were still on the horizon.
