recalculated as if the individual had been born in the new place of residence instead of
the actual place of birth. In this, ACG differs from much older locational tech-
niques, most of which relate geography directly to parts of the celestial sphere. The
best-known classical example of these older, “geodetic” techniques is Manilius’s first
century C.E. ascription of areas of the ancient world to signs of the zodiac.
In contrast, ACG works by determining where on Earth the 10 astrological
planets were angular at the moment of an individual’s birth, that is, where any one of
them was rising, setting, straight overhead, or anticulminating (straight underneath).
For example, even though it may have been nighttime at the actual place of birth, at
the moment of birth the Sun was rising someplace else on Earth. All the various local-
ities where the Sun was rising at that moment can be displayed as a line drawn across a
map of the world. Such a line is labeled SU ASC (SUn on the ASCendant) on an
ACG map; with 10 astrological planets and four angular positions, the map will be
crossed by 40 lines in all.
Interpreting an ACG map is easy: Since being angular enhances the expres-
sion of a planet’s nature in the personality, affairs symbolized by the planet can be
expected to be more prominent in the life of an individual who travels through or
resides under an SU ASC line on such a map. By moving to a locality under an SU
ASC line on one’s ACG map, an individual can expect more self-confidence, the-
atricality, creativity, and leadership to manifest.
Although the idea of preparing such a map for applications in mundane astrol-
ogy occurred to other (for the most part sidereal) astrologers in the early part of the
twentieth century, it was only the development of modern computers that made maps
easily enough attainable for their value to be recognized in individual astrology.
AstroCartoGraphy pioneered the provision and interpretation of maps to tens of
thousands of individuals who, by comparing their life experiences to the angular plan-
ets identified by the map, have confirmed ACG to be among the most reliable natal
astrological techniques. It works so well because it uses only the relevant planet and
angles, the two most tangible and indisputable of astrological data.
Since most people have resided at several locations during their lifetime, an
ACG map can confirm impressions of earlier residences as well as forecast outcomes
of future moves. Moreover, a location’s planetary identity seems consistent even when
dealt with remotely, as, for example, through people who at one time lived at a partic-
ular place or have investments or other indirect involvement there. Many people
have reported that love mates were born near a place where Venus was angular, or that
they met in such a zone.
In ACG, planet angularities are calculated by oblique ascension, that is,
when the planet is bodily on the meridian or horizon, rather than when its zodiacal
degree rises or culminates. Where two lines on an ACG map cross, they identify a
place at which two planets were simultaneously angular at the moment of birth (e.g.,
one rising while the other occupied the midheaven). In addition to collocating a
place-specific interoperation of the two planets’ energies, this paran (line crossing)
also establishes a latitude at which the two planets’ energies are related anywhere on
Earth; that is, a crossing of any two lines on an ACG map creates a special latitude
