Medieval Predictive Astrology:  The Renaissance

The philosophical worldview taken by Regulus Astrology LLC primarily rests on teachings of the ninth century Arabic Astrologer Abū Ma’shar.   This style of astrology is a blend of Babylonian, Greek, Persian, and Islamic influences which reached its intellectual height during the Islamic Golden Age.  Beginning in the 12th century, a wave of translations helped bring the collected scientific knowledge of Arab Civilization to Western Europe in what many historians now define as the 12th Century Renaissance, a predecessor to the more well-known European Renaissance dating from the 14th to 17th centuries. 

Not unlike prior periods of intellectual renaissance, the modern era has witnessed a revival in older methods of astrology.  Approached from the perspective of the history of science, academics including Otto Neugebauer, E. S. Kennedy, and David Pingree led the first wave of translations in the second half of the 20th century.  Robert Zoller’s translation of Bonatti’s On Arabic Parts in the early 1980s helped open the door to this forgotten field for contemporary astrologers.  In 1993, Project Hindsight organized the first serious stab at translating Arab, Greek, and Hebrew texts for the practicing astrological community.  The co-founders of the project were Robert Schmidt, Robert Zoller, Ellen Black, and Robert Hand.  With a focus on the Hellenistic tradition, the work of Project Hindsight continues today under the guidance of Robert Schmidt.    

The 2007 publication of Bonatti’s complete Book of Astronomy, translated by Zoller student Ben Dykes marked an accelerated unmasking of works from prior eras.  It is expected that within the next ten years the majority of surviving ancient astrological texts will be available in English translation. 

Regulus Astrology LLC:  Research Projects

Since 1980, most of the revival of Medieval Predictive Astrology has concerned itself with history, translation of texts, and transmission/impacts on culture.  As important to understanding the practice of astrology as these topics are, there is no guarantee that these ideas remain relevant and their stated methods actually work.  What is required is systematic testing of the assumptions and models behind Medieval Predictive Astrology.  To this goal Regulus Astrology LLC dedicates its research efforts.

Completed Research Projects:  Rectification

A Rectification Manual: The American Presidency is designed to provide concrete answers on the mechanics of medieval predictive methods:  how they can be systematically employed, taught, and practiced by contemporary astrologers viewed through the lens of natal chart rectification.  As the book’s introduction makes clear, there is no current consensus on rectification because the modern predictive toolbox is grossly under specified.  A three stage rectification method is proposed which incorporates the full gamut of medieval predictive techniques.  Their application is sequenced such that the robustness of each method is commensurate to the level of uncertainty encountered during each stage of the rectification process.  

Rectification is an important prerequisite to reconstructing the medieval astrological model because delineation and prediction methods cannot be tested, studied, or learned if data is incorrect.  Astrologers have long realized the limitations of sloppy data and have compiled substantive data sets for research, with birth data verifiable by an official birth certificate the standard.  Yet even the most meticulously verified birth data falls short of what is actually required to test medieval predictive techniques like primary directions.  An error in birth time as small as a few minutes generates an error of a year or more when using directions as a predictive tool.  In order to recover the medieval astrological model, a compilation of several hundred accurately timed to-the-second nativities will be necessary.  The forty-two Presidential nativities included in A Rectification Manual are a good start.

Current Research Projects:  Essential Dignities and the USA Independence chart

Essential dignities represent the core building blocks of astrological delineation and prediction.  Yet systematic tests on the choice of triplicity, bound, and decan rulers are missing from the literature.  A Rectification Manual presents evidence favoring Dorothean triplicity rulers and Egyptian bounds and suggests methods for conducting tests on a wider sample.  The book uses Chaldean decan rulers for al-mubtazz table scoring, but recognizes the alternate set of decan rulers based on the triplicity of signs more accurately judges physiognamy (physical appearance).

Conducting further tests on Egyptian versus Ptolemy’s bound rulers is one area of current research.  The ability of significators to produce consistent changes as they move through the Egyptian bounds by primary motion for a single figure (“Directing through the Bounds”) is one of two ways that competing sets of bound rulers can be tested.  It’s a challenge I have taken up in rectification of America’s July 4, 1776 Declaration of Independence chart.  The rectification is complete and features a Sagittarius Ascendant, slightly later than the well-known Sibly figure.  So far, subjecting the Ascendant to the Directing through the Bounds method has timed every major social movement in American’s history – and this is just the tip of the iceberg.  It’s a finding so revolutionary that in my estimation it will not only forever settle the debate over choice of bound rulers but the correct USA figure as well.  It’s an exciting project which will be released during 2008.

Research on the application of decan rulers to judging physiognamy will follow.
