Chronology of Astrological and Historical Developments
Edmond H. Wollmann
First Version Sept 17, 2000 - Second version March 15, 2001
Lee Lehman and Demetra George advising
The following partial chronology juxtaposes the major
political and societal developments in the areas of the world, with records of
concurrent astrological and astronomical developments for the same time periods.
The importance of these developments (in the European) is the degree with which
the psychological control factors of both government and religious hierarchies
begin to usurp individual rights and freedoms of the individual to empower
themselves through the knowledge of astrology, and/or to seek an understanding
philosophically of their own place within the universe. In the pre-hispanic
periods of the Americas identified, most of the native cultures were for the
most part balanced between the feminine and masculine, and Teotihuacan (where
the gods have a road) in Mexico was a society that worshipped a Goddess. The
Pyramid of the Sun in Teotihuacan was built to allow the entrance of the cave
underneath it to align with the setting of the Pleiades. Mesoamerica will be
defined as the area from Mexico to Honduras.
In Europe, the feminine aspect of support through trust
begins to wane by the first half of the first millennium B.C.E.. This reflects
the gradual development of the indoctrination of philosophic notion of the
individual as "inherently negative" belief system. This negative
belief system lead to the Christian cult and the concept of being born already
at disadvantage (sinner). This indoctrinating system of denigration is meant to
keep the individual in a state of perpetual guilt and "amends making"
schemata of personal perspective of never-ending self justification, and empty
self-efficacy orientation that requires "guidance" from those in
"authority." Hence, the competition and alignment of the church and
Rome over the centuries. Power is the issue in this area of the world. This is
created by the collective because of their unwillingness to take responsibility
for their own reality. Hence, the "science of following" (religions) and
its development are essentially what is indicated as the societal structures
move from trusting the environs to needing to control them.
Introspection and concepts of abundance remained high in the
pre-hispanic Americas, and sacrifice being noble death was accepted as positive,
which all but eradicated societal structures based on fear of scarcity. As
self-introspection and beliefs in resourcefulness wanes, so does the belief in
the ability to decide one's own fate. As self-efficacy wanes (because of the
cutting off of the belief in the ability to self-empower), an increase in
fatalistic philosophies and despair also increases (leading eventually to the
despair of the dark ages in Europe). The increased discounting of the
environment as being instructive and instead being evil (Christian philosophic
perspectives and the increase in the masculine dominance perspectives) reflects
this downward spiral of dis-empowering tactics designed by those in power to
control increasing populations and prevent the egalitarian natural state
understood instinctively by early cultures, and those in the Americas prior to
the Spanish "holocaust." The Mesoamerican cultures, therefore, never
really ceased using astrology and the archetype of the Cardinal points. It was
alive and well and most of its documentation destroyed by the Spanish Christian
Monks justifying it as "evil." Only a few historical documents remain
from the Maya, which is why it has been so tedious to decode them. The evidence
is, that Mesoamerican cultures (the Olmec being the formative culture) were not
unlike Babylonian cultures in their reverence for the cycles of Venus, worship
of the goddess, nature and the heavens in general.
