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 (Greco-Roman) 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.
Current Research Focus (updated April 2010)
Recently I have worked on physiognomy, temperament, and
manners; all techniques used to construct a natal medical
and psychological profile. Currently I am spending most of
my time with astrological physiognomy with the goal of fine
tuning models for predicting physical appearance. Since
physiognomy and temperament have the same basis in humoural
physiology, getting a better grip on physiognomy opens a
backdoor to temperament theory whose models should
theoretically use the same set of significators.

Natal Astrology
I. Rectification
+A Rectification Manual: The American Presidency
A Rectification Manual: The American Presidency
(December 17, 2007) 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.

II. Delineation
+Longevity
Whether a child will be stillborn, take nourishment,
survive infancy, or survive to adulthood was considered the
first delineation topic in natal astrology for medieval
astrologers. Chapter 4 “The Arcus Vitae” in A
Rectification Manual proposed a model for computing the
hīlāj (“root of life”) based on methods of Al-Qabīsī and
Bonatti. A discussion of the al-kadukhadāh (“giver of
years”), the killing planet, and the arcus vitae follows.
Appendices C and D includes worked out examples of this
methodology for thirty-nine American Presidents and
forty-one First Ladies.
+Physiognomy
Defined as judging character from bodily features by the
Greeks in the 4th Century BCE, physiognomy was
first developed by a group of medical-philosophers operating
outside the scope of astrology. Beginning with Ptolemy,
astrologers split judgments of physical appearance and
character into two separate categories. What is now
referred to as astrological physiognomy is limited to
physical appearance of the face and body. For character,
see the heading for ‘Manners’ below.
Astrological Physiognomy: History and
Sources (April 20, 2010). A comprehensive literature
review of astrological physiognomy from the Greco-Roman
period to the present day. Includes works canonical to the
non-astrological physiognomy tradition beginning with the
pseudo-Aristotelian Physiognomica (3rd Cent BCE). 71
pages.
Astrological Physiognomy: Empirical Tests of the Leo
Rising Decan (April 16, 2010). A test of methods for
predicting the shape of the face based facial models of John
Willner (1991) and the rising decan (Hindu decans).
Majority of examples support the Sun’s sign and not the
Sun’s season as the contributor to physiognomy. Study
raises questions on inclusion of Sun’s season in temperament
models as recommended by Ptolemy. Thirty-six examples.
Horoscopes sourced from Astrodatabank; no rectified charts
used. 57 pages.
+Temperament
The four primitive qualities, the four elements, the four
humours, and the four temperaments are concepts created by
Greek medical-philosophers between the 5th and 3rd
centuries BCE. Labels for the four classical temperaments -
sanguine, choleric, melancholic, phlegmatic - were in common
use during Medieval and Renaissance periods. Initially
meant to define an individual’s humoural balance for medical
applications, descriptors for the classical temperaments
were later expanded to include personality and were used to
great effect by writers (Chaucer) and playwrights
(Shakespeare) for stock character development. As used by
modern 21st century psychologists, the concept of
temperament is exclusively oriented to personality.
Temperament and Manners: A Medieval Astrological
Profile of Abraham Lincoln (February 16, 2009). A
preliminary paper using temperament models of Greenbaum and
Frawley predicted a primary phlegmatic temperament which is
at odds with Lincoln’s well-known and documented primary
melancholic temperament. Lincoln’s known depressive
episodes are compared with dates computed by directing
Saturn (significator of melancholy) to the Ascendant, Moon,
and Sun. 24 pages.
I plan on revising this paper after I have concluded
additional research on physiognomy. One missing feature of
astrological temperament models appears to be modification
of temperament by chronic disease delineated by the 6th
– 12th house axis. For Lincoln, the Venus/Aries –
Mars/Libra opposition ruling the 6th – 12th house axis
appears consistent with John Sotos’ diagnosis of multiple
endocrine neoplasia type 2b (MEN2B), a genetic cancer which
most often forms in the thyroid and adrenals glands. Sotos
(The Physical Lincoln, CreateSpace, 2008, ISBN
978-1440420146) correlates MEN2B with Lincoln’s physical
features associated with the melancholy temperament. With
Venus ruling the thyroid and Mars ruling the adrenals (and
both afflicted in Lincoln’s horoscope), Sotos’ thesis is
consistent with a chronic disease of the 6th -12th house
axis which fundamentally modified Lincoln’s physical
appearance and temperament. 24 pages.
+Manners
Judgment of manners (or “soul”) differs from temperament
by including the Moon and Mercury and their rulers as
significators. Prediction of either good or evil behavior
is derived from this delineation exercise. It is the
medieval equivalent to what modern psychologists would label
as personality.
American Spree Killers: Delineating Evil in the Natal
Horoscope (in preparation). Considers four models for
evil as a predictor for mass murder: Moon’s configurations
(a/c Maternus), Ruler of the Chart (a/c Ibn Ezra), Manners
(rulers of Ascendant, Moon, and Mercury), Fixed Stars (when
configured with one or more significators of manners), and
Temperament (a/c Ribiero). First compiled as individual
posts in the members area in the summer of 2009, I am
currently editing entries to for presentation in a single
document.
+Wealth
Central to the list of significators for wealth is the
lot of fortune, the most well-known lot of approximately one
hundred. Lots are computed zodiac positions based three
horoscopic inputs. The lot of fortune (for diurnal figures)
is computed by projecting the distance taken from the Sun to
the Moon from the Ascendant. For nocturnal figures, the
computation is reversed, e.g., the distance from the Moon to
the Sun is projected from the Ascendant. There exists some
ambiguity in the literature for nocturnal figures whether or
not the computation should be reversed. Using data for
twenty-two American Presidents, “Appendix B: Tests of Sect
Influence: Part of Fortune/Fidaria” in A Rectification
Manual confirms the validity of the reversed formula for
nocturnal figures.

computation of all lots is available for download from the

III. Prediction
+Fidaria
Fidaria is a time lord technique believed to be of
Persian origin created during the Sassinid Empire. Fidaria
entered the Medieval Arabic tradition during the translation
wave initiated by the Abbasid Caliphate beginning 750 CE.
What is controversial is an alternate sequence of planetary
time lords for nocturnal figures. Insertion of the North
Node and South Node Fidaria period following the major Mars
period for nocturnal figures is recommended by Robert Zoller
and confirmed by analysis for twenty-two American
Presidents. See “Appendix B: Tests of Sect Influence: Part
of Fortune/Fidaria” in A Rectification Manual for
details.
+Primary Directions
As
practiced by Medieval astrologers, primary directions
occupied a central, if not the highest position, within the
predictive hierarchy. Long abandoned for their mathematical
complexity in favor of the easier to calculate secondary
progressions, primary directions have been revived within
the last ten years by traditional astrologers.
Primary
Directions Notation: Towards a Uniform Presentation Standard
(April 21, 2010) is an adapted excerpt from the User’s
Guide to my second book America is Born. Suggested
is a uniform method for primary directions notation for
citations in articles and books.
Primary
Direction Sequence. In using primary directions as one
predictive tool for natal chart rectification, I made an
important discovery named the ‘Primary Direction Sequence’
which proposes a different solution to treatment of latitude
for directing aspects. The Primary Direction Sequence is
explained in both of my books and the following book review
of Martin Gansten’s 2009 book on primary directions.
Directing through the Bounds (a.k.a. “circumambulations”).
A more specialized application of primary directions is
named Directing through the Bounds which is a sophisticated
Hellenistic time lord technique best described in Abū
Ma’shar’s book on solar returns. My second book America
is Born features a comprehensive example of the
Directing through the Bounds technique.
Book
Review: Primary Directions: Astrology’s Old Master Technique
by Martin Gansten (October 6, 2009). The bulk of the
review debates the limits of primary directions theory. An
unabashed supporter of the Ptolemaic semi-arc proportional
method of directing, Gansten disputes many later
permutations of primary directions on theoretical grounds.
A case in point is a dispute over directions computed for
George Washington presented in A Rectification Manual:
The American Presidency. Submitting Washington’s
rectification to another round of empirical tests, I
consider a total of twenty-nine primary directions of
Jupiter to the angles for the Revolutionary War Era
(1768-1783). 66% these directions corresponded with life
events which matched the direction’s delineation within 1
week or less; 97% did so within 1 month or less. In
addition to shedding light on the validity of additional
permutations of primary directions, this empirical study
outlines a six-step approach for delineating the promise of
a given primary direction. Results continue to support the
validity of Egyptian bounds and the ability of the
Primary Direction Sequence to generate a series of
events within a discrete time period based on both zero and
full latitude assignment to planets and their aspects.
Primary
Directions: The Practice Manual (201X). I have
committed to writing a book on the technique of primary
directions. Like all of my publications, the style will be
empirical and supported by worked out examples of
financiers, politicians, and religious figures. Its
publication date is not in the immediate future.
Mundane Astrology
+The Regulus USA National Horoscope
Ever since Ebenezer Sibly first
introduced his proposed horoscope for the Declaration of
Independence in his 1780 book “The Celestial Science of
Astrology”, agreement on the correct USA National Horoscope
has proven elusive with over a dozen different horoscope
variations proposed. America is Born: Introducing the
Regulus USA National Horoscope (November 25, 2008) is
unique for its application of medieval astrological
techniques to the question of modern National Horoscopes.
Included as a special application of primary directions is
the largest empirical study of Directing through the Bounds
ever attempted or presented. Results that the directed
Ascendant times shifts in the national consciousness
represent a significant contribution to the history of
American social movements.
Available for download in the member’s
