Constellational Astrology

Recently I’ve gotten interested in what has been called “astronomical astrology” or “true sidereal astrology” which is a form of sidereal or fixed-star-based astrology in which the planets are located in the actual constellations or star groups as they appear in the sky. For example, if you were born with the Moon in the middle of the group of stars we call Leo, your Moon would be considered a “Leo Moon” rather than being a Moon in the tropical sign Cancer. Constellational astrology is a kind of “what you see is what you get” form of the art, which is based strictly on direct observation of the position of planets in the sky against the backdrop of the fixed stars.

While both tropical and sidereal astrology divide the zodiac into equal 30-degree signs, “constellational astrology” partitions the zodiac circle (or path of the Sun) into thirteen constellations of unequal size. Some constellations are bigger than others and occupy more space along the zodiac. In addition, the foot of the physician snake-bearer constellation Ophiuchus crosses the zodiac circle, so that Ophiuchus is allotted a portion of the zodiac circle. The image below shows how Ophichus occupies about 18.6 degrees of the ecliptic (the blue line) between Scorpio and Sagittarius.

The IAU boundaries of constellations allot a large portion of the ecliptic to Ophiuchus and cut off a significant part of Scorpio which also spans much of the same region and has many brighter stars than Ophiuchus. The rationale for this IAU boundaries is puzzling and probably incorrect, given the obvious greater prominence of the stars that constitute Scorpio near this segment of the ecliptic.

Ophiuchus is associated with the myth of Asclepius , the noted healer of Greek legend, but he may also be related to the Babylonian god Nirah, a serpent deity whose upper half was human and lower half consisted of serpents for legs (not unlike Sagittarius whose upper half is human and lower half is that of a horse).

Asclepius in mythology represents the healing aspect of the medical arts..

As mentioned, each IAU designated constellation will occupy a distinct portion of the ecliptic circle. The following lists gives the number of degrees along the ecliptic that is allotted to each of the 13 zodiacal constellations (note that these are star-groups rather than the traditional “signs” of the zodiac which are always 30-degrees in length). The listing is compiled for the date J2000.0 and gives the number of ecliptic degrees in each constellation along the ecliptic, the duration in days and the date on which the Sun enters that constellation. In the IAU conventions for boundaries of zodiac constellations, the Sun spends only 6 days passing through the Scorpio portion of the ecliptic, which is rather bizarre and probably indicates how out of touch the IAU astronomers who developed this system were with the history of astronomy.

  • Aries: 24.7303 degrees (lasts ~ 25 days, starting around April 18 Gregorian)
  • Taurus: 36.7229 degrees (lasts ~ 37 days, starting around May 14 Gregorian)
  • Gemini: 27.8479 degrees (lasts ~ 28 days, starting around June 21 Gregorian)
  • Cancer: 20.0504 degrees (lasts ~ 20 days, starting around July 20 Gregorian)
  • Leo: 35.8124 degrees (lasts ~ 36 days, starting around August 10 Gregorian)
  • Virgo: 43.9593 degrees (lasts ~ 45 days, starting around September 16 Gregorian)
  • Libra: 23.2372 degrees (lasts ~ 23 days, starting around October 31 Gregorian)
  • Scorpio: 6.5905 degrees (lasts ~ 6 days, starting around November 23 Gregorian)
  • Ophiuchus: 18.5999 degrees (lasts ~ 19 days, starting around November 29 Gregorian)
  • Sagittarius: 33.4184 degrees (lasts ~ 34 days, starting around December 17 Gregorian)
  • Capricorn: 27.8315 degrees (lasts ~ 29 days, starting around January 19 Gregorian)
  • Aquarius: 24.1635 degrees (lasts ~ 24 days, starting around February 16 Gregorian)
  • Pisces: 37.0368 degrees (lasts ~ 38 days, starting around March 12 Gregorian)

For dates other that J2000.0, the values in the above listing for the number of degrees per constellation along the ecliptic will vary slightly due to precession as the ecliptic will tilt slightly with respect to the Earth’s equator. For example, in the year 0, Ophiuchus occupies 18.5672 degrees along the ecliptic. By the year 1000, Ophiuchus was covering 18.5834 ecliptic degrees; in the year 2000, 18.5999 degrees; and in the year 3000, Ophiuchus, due to the tilting of the Earth’s axis in its precession, will span 18.6167 degrees.

Now that we have established the sizes of the IAU designated constellations, a standardized measure agreed to among astronomers, all that remains is to determine where to start the zodiac, that is, which point to choose as 0 degrees of the constellation Aries. As usual, there are differing opinions about which value to select as the ayanamsa (the difference in degrees between the starting point of tropical and the sidereal zodiac).

For example, one site by Bruce McClure, using the boundaries for constellations set by the International Astronomical Union in the 1930s. notes that on 19 April 2019 the Sun entered the constellation Aries at 29.09 ecliptic degrees of tropical sign Aries. This corresponds to a chart set for 11:33 AM BST in Greenwich, UK, on 19 April 2019 (as calculated in Solar Fire v9.0.26). In the sidereal zodiac with the popular Lahiri ayanamsa, this would place the Sun at 4 Aries 58 sidereal. Thus, if we were to add 4 degrees 58 minutes to the Lahiri ayanamsa for the year 2019, we would place the Sun at 0 Aries sidereal.

Another site, in a video by sidereal astrologer Athen Chimenti, uses a “custom” ayanamsa in which the fixed star Beta Aries (Sharatan) is set to occupy 2 Aries 15 in the “true” sidereal zodiac. This star near the beginning of the star-group Aries was at 3 Taurus 58 tropical in the year 2000. With the Lahiri ayanamsa this star would lie at about 10 Aries 07 sidereal. If we were to add about 7 degrees 52 minutes to the Lahiri ayanamsa for the year 2000, it would place Beta Aries at 2 Aries 15 sidereal.

Athen Chimenti also uses values that differ some from the IAU constellation boundaries. Because the constellations along the ecliptic may overlap or have small gaps between them, Chimenti uses the midpoint between constellation boundaries as the demarcations points between them. Because the boundaries are not sharply defined, he considers the region within 3 degrees of such boundaries to reflect a blend of both constellations. The following list gives the approximate dates for which the Sun traverses each constellation in Chimenti’s system, which appears to be more consistent with observation of the heavens and the traditional constellation boundaries than the somewhat arbitrary IAU divisions.

Next let’s consider where to start the “true sidereal” zodiac.
One choice for beginning the CONSTELLATION ARIES is to position the fixed star Sheratan (Beta Aries) at 2 Aries 15 of the sidereal zodiac as a reference point.

Looking at the sky with the program Stellarium, we can see the issue more clearly. According to the sky maps, the Sun in the year 2020 should enter the constellation Aries around April 20, 2020, as can be seen in the following images, which show the transiting Sun moving along the ecliptic at a position around the end of the constellation Pisces and the beginning of the constellation Aries.

Sky on 20 April 2020

These images are set for the period when the Sun is leaving the constellation Pisces and entering the constellation Aries. On April 20, 2020, the star Alrescha at the end of Pisces has a tropical ecliptic longitude of 29d 40m 04s. At the same time the earliest star in constellation Pisces on this map, Mesathrim, has an ecliptic longitude of 33d 28m 23.8s. Thus, the boundary between the constellations Pisces and Aries should lie somewhere between these values. If we were use the midpoint between these two stars, we would place the boundary between Pisces and Aries at 31d 34m 14s of ecliptic longitude on 20 April 2020. In the sidereal zodiac with the Lahiri ayanamsa this boundary would like at 7 Aries 26 of the Lahiri sidereal zodiac. Thus, if we were to add 7 degrees 26 minutes to the Lahiri ayanamsa for the year 2020, we would place the Sun at 0 Aries sidereal in this star map. This value which we derived from Stellarium is very close to that used by sidereal astrologer Athen Chimenti, namely a “custom” ayanamsa in which the fixed star Beta Aries (Sharatan) is set to occupy 2 Aries 15 in the “true” sidereal zodiac as a standard of reference.

Below is a section of a chart cast in the “true” sidereal zodiac with Beta Aries set at 2 Aries 15 as a reference point.

This chart, from a video by Athen Chimenti, is cast in the “true” sidereal zodiac with unequal constellations which shows the positions of the planets in the constellations as they actually appear in the sky. The symbol in the black space between Scorpio and Sagittarius is the constellation Ophiuchus.

Here is the same chart as the one above but cast in the tropical zodiac with Placidus houses.

Author Vasilis Kanatas, who wrote about about incorporating the constellation Ophiuchus into the zodiac circle, gives a somewhat different set of values than those discussed above. According to Kanatas, the number of days the Sun spends in each constellation as it travels around the ecliptic are as follows:

Number of Days in Each Sign

Aries: 25.5 days
Taurus: 38.2 days
Gemini: 29.3 days
Cancer: 21.1 days
Leo: 36.9 days
Virgo: 44.5 days
Libra: 21.1 days
Scorpio: 8.4 days
Ophiuchus: 18.4 days
Sagittarius: 33.6 days
Capricorn: 27.4 days
Aquarius: 23.9 days
Pisces: 37.7 days

The following table gives the values suggested by author Vasilis Kanatas for the year 2000.

For further comparison of the “true sidereal” chart with the tropical and sidereal zodiacs, I compared a chart cast in true sidereal with the Kanatas ayanamsa in the program Prometheus with its tropical and Lahiri counterparts. The chart is cast for 30 April 2017 at Noon EDT in NYC. Note the unequal sizes of the 13 constellations along the ecliptic.

30 April 2017, NYC, Noon EDT, “true sidereal zodiac” using the Kanatas ayanamsa and showing the positions of the planets in the 13 constellatons of the zodiac along the ecliptic.

In the above “true sidereal” chart (Kanatas ayanamsa), the Sun lies at 11 Aries 33. The tropical chart calculated for the same moment and location in Solar Fire has the Sun at 10 Taurus 29, a difference of 28 degrees 56 minutes between the “true sidereal” and the tropical positions. The same chart cast in the sidereal zodiac with the Lahiri ayanamsa places the Sun at 16 Aries 23, a difference of 4 degrees 50 minutes from the Kanatas value. For comparison, below is the same chart (30 Apr 2017) cast in the tropical zodiac with Placidus hosues.

It appears that different authors are in the same ballpark but are not in strict agreement about when to start the “true sidereal” zodiac (0 Aries sidereal) or about the size of the portion of each of the 13 constellations that lies across the zodiac circle.

Addendum (5 May 2020): The two systems in common use appear to be those of Athen Chimenti and Vasilis Kanatas, so I put together a table comparing them. The table lists the starting point of each “true sidereal” constellation as measured in ecliptic longitude from the Vernal Equinox of 19 March 2020 and also gives the span along the ecliptic of each sidereal constellation in each system. Chimenti’ takes into account the overlap and gaps between constellations on the ecliptic and uses the midpoints of their boundaries as points of demarcation. He claims that his measurements are more in sync with the actual view of the sky. Kanatas appears to be using the IAU astronomical conventions for the sizes of the constellations. I also included the mean value of the Chimenti and Kanatas systems.

Because the boundaries between the actual constellations in the sky are somewhat a matter of opinion, Chimenti advises considering planets within about 3 degrees of the boundaries as having the properties of both constellations. As you can see in the table below, the greatest area of disagreement appears to be for the constellations Scorpio and Ophiuchus. In my opinion Chimenti’s approach is more consistent with traditional constellation boundaries that the IAU-based approach of Kanatas.

Addendum (12 May 2020):

In addition, I came across an excellent video by Gemini Brett which critiques the constellation boundaries drawn by IAU and used by NASA, especially the area of the zodiac where Scorpio and Ophiuchus overlap. It is a video well worth watching. The discussion of constellation boundaries begins a little over an hour into the video.

Finally, I also found a listing of constellation boundaries and sizes in the book Scientific Hindu Astrology by P.S. Sastri, Vol. I, p.187 (2001), which I have copied and pasted below:

Your Smartphone Can Help During This Pandemic

This blog is normally about astrology and tarot, but today I make an exception. In a recent article about SILENT HYPOXIA by Dr. Richard Levitan in the NY Times, the doctor commented on what he learned treating Covid-19 pneumonia at Bellevue Hospital. Specifically, he found that “these patients did not report any sensation of breathing problems, even though their chest X-rays showed diffuse pneumonia and their oxygen was below normal.” Apparently those sick with Covid-19 were suffering from silent hypoxia in which they had severely low levels of oxygen in their blood despite the lack of apparent symptoms. The low oxygen levels were not discovered until the disease had progressed to dangerous levels. Dr. Levitan wrote: “Normal oxygen saturation for most persons at sea level is 94 percent to 100 percent; Covid pneumonia patients I saw had oxygen saturations as low as 50 percent.” The next stage of the illness is often respiratory failure and the need for a ventilator.

The doctor recommended the following: “There is a way we could identify more patients who have Covid pneumonia sooner and treat them more effectively — and it would not require waiting for a coronavirus test at a hospital or doctor’s office. It requires detecting silent hypoxia early through a common medical device that can be purchased without a prescription at most pharmacies: a pulse oximeter.”

Here’s where your smartphone comes in. Many mobile phones have a built-in pulse oximeter. My own phone is a Samsung, and the Samsung Health app has a feature to measure “stress level” which includes heart rate and blood oxygen levels. I have tested my Samsung phone on many occasions over the past year against a commercial pulse oximeter used in a hospital and the results were identical, so it is very accurate. I don’t have an iPhone, but I assume that Apple products probably have a similar feature.

Simply by checking our levels of oxygen daily to make sure they stay in the normal range (above 93%) is a way of tracking whether the virus is silently affecting our lungs. Our smartphones can be a useful tool in keeping us healthy during this crisis.

Evangeline Adams ‘New Horary’ — Will I pass the exam?

In the previous post I surveyed some of the literature about horary charts that deal with academic examinations and looked at a couple of charts. In this post I’d like to consider Evangeline Adams “new horary” method as applied to such questions. Adams, who spent about a half hour with each client, developed a quick method of doing horary which differed from the traditional method taught by Lilly. Because she was already intimately familiar with the client’s natal chart, she sought a way to quickly use what she knew about the birth chart to answer horary questions that came up during the 30-minute consultation.

Although Adams does not clearly spell out the theoretical rationale behind her horary method, she must have reasoned somewhat as follows. The birth chart depicts the natal promise. Nothing happens in the life of the querent that is not somehow indicated in the birth chart. Every 24 hours the Earth makes a full rotation so that at any given moment a particular factor in the natal chart gets highlighted by the nature of the horary Ascendant and the relative positions of the natal planets in houses of the horary wheel. Thus, by placing the positions of the planets at birth in the horoscope of the moment of the horary question, the astrologer is able to read which factors in the birth chart are prominent and how this natal promise will play out in the life of the querent.

Traditonal astrology uses the planetary hour of the horary chart to indicate “radicality”. Why should this be so? My hypothesis is that the planet ruling the hour of the question forms a link between the horary and the natal charts. Whatever role the horary hour lord plays in the birth chart comes to the forefront at the time of the question. An example chart will illustrate what I mean.

The following chart was posted in a horary forum to which I belong. The author of the chart gave permission to reproduce it here, but I have withheld identifying information out of respect for her privacy. The querent was taking a history course at the university and asked whether she would pass the exam. She was using Regiomontanus houses and Ptolemaic terms/bounds. Here is the chart she posted: inner wheel is the horary, outer wheel is her natal chart.

Inner wheel: Horary chart – Will I pass the history exam? (Asc = 14 Aquarius 12. MC = 7 Scorpio 57.)
Outer wheel: natal chart.

To make it easier to read, below is the original horary chart without the natal planets.

Will I pass the exam? — Original horary chart without natal planets outside. Mars day, Saturn hour.

This is a reasonably favorable chart, so she should pass the exam. The question was asked on a Mars day during a Saturn hour. Saturn rules the Ascendant and is dignified in its domicile Capricorn. The Sun, a general signifier of success, is prominent in the 10th near the MC and applies to sextile Saturn. The Moon, which co-rules the querent and conjoins the Ascendant rapidly applies to trine Mars, which rules the 10th (honors, success) and occupies the 9th of higher education. The Moon does not occupy any of the dignities of Mars, so the success on the exam will be modest at best due to the lack of dignity.

Now let’s look at the natal chart (outside wheel in the first horoscope above) to see what role the horary hour ruler Saturn plays in the birth chart. Here is the natal chart:

Natal chart of querent with Regiomontanus houses and Ptolemaic terms.

The horary hour lord Saturn occupies the 9th house of higher education in the birth chart and has dignity only by face, indicating a serious attitude toward university studies but also the potential for difficulties in this area of life. Saturn also rules the natal 9th house. Saturn’s closest aspect is a square with Venus, ruler of the 12th house. Thus, the astrologer, simply knowing that the horary question was asked during a Saturn hour, could say that the query has to do with Saturn issues in the birth chart which probably relate to difficulties with higher education. In her own discussion of the horary question the querent said that higher learning “has always been highly prized by me but studying never came easy.”

Now let’s look at the Evangeline Adams horary for this question. She simply placed the natal planets into the horary wheel and ignored the transiting planets at the moment of the question.

Qurent’s natal planets placed into horary wheel.

The above chart is what Evangeline Adams would have used to answer this querent’s question. The question was asked on a Mars day during a Saturn hour.

Saturn rules the Ascendant and the 12th Regiomontanus house cusp. By exaltation Saturn rules the 9th house of higher education, which it occupies in the birth chart. Adams was thoroughly familiar with the natal charts of her clients, so she could readily call upon the natal symbolism when looking at the horary charts.

Saturn’s only dignity is by face, so the querent will have to struggle to get what she wants. It is favorable that Saturn, as exalted ruler of the 9th, lies in the 1st because this gives the 1st-house querent some control over the outcome of 9th house matters. Lilly uses the exalted rulers of houses as significators in his delineations, for example in his question about buying the houses of Master B (CA 220). When I saw this chart in the horary forum, I wrote the following:


The 12th part of the horary ASC at 14 Aquarius lies in Cancer, which is on the 6th house cusp. The Moon rules Cancer and lies in the 1st conjunct the Ascendant, perhaps indicating a focus on hard work and personal initiative regarding the question. Moon’s next aspect is a trine to Mars, ruler of the 10th in the 9th of higher education. This is a positive indication and suggests that the hard work in her studies will pay off on the exam.

If we look at the Adams chart with the natal planets in the horary wheel, we see that the horary hour lord Saturn lies in the natal 9th house. This is fitting because the question is about higher education. In addition, the natal Moon conjoins the cusp of the natal 9th, again indicating that higher education is on the mind of the querent when she asks the question. Venus rules the 9th and Mars rules the 10th. There is no applying aspect between the Asc ruler Saturn and either Venus or Mars, so we need to consider collection and translation of light.

In the Adams chart Venus is separating from a square to Saturn (querent) and applying the a sextile with Mars (10th ruler of honors and success). In addition, the 12th house moon (ruler of the 6th) is separating from a sextile to Mars in Aries (10th ruler, honors & success) and applying to the exalted Sun, ruler of the 7th and a general signifier of success.

Most likely this was a difficult exam and required a lot of 6th house agonizing and hard work, but the querent passed the exam in the end.


Interestingly, translation and collection of light often imply the involvement of a third party in the resolution of the question. In this case the querent commented that she had worked with a tutor in addition to the lecturer who taught the course. She wrote this about the final outcome:

I did pass. I wasn’t prepared as I thought, because my tutor led me to believe that I should just focus on certain parts of what I’ve already learned and not taken into account that it was overall. Apparently, my recall was good enough on the day. Anyway, the overall mark was 60% and the best I could hope for.”

In addition, I’d like to call attention to a comment which Ema Kurent made in reference to my previous post on this topic: “always look at what the chart is saying to you, where it is leading you. There should be harmony between, and strength of, the 1st, 10th, with some links to the 3rd or 9th rulers. Sometimes, a harmonious applying aspect of the Moon to the Sun can give an affirmative answer, even without finding the ‘correct’ house. I tend to be very flexible with the exam questions.” In this horary chart, the querent’s Moon applies to perfect a sextile with the Sun, exalted in Aries in the 3rd house which is associated with education.

Horary: Will I pass the exam?

The 17th century astrologer William Lilly did not discuss questions about examinations in his classic text on horary astrology (1647), so modern horary astrologers are somewhat left to their own devices in answering such questions. One can find references in the modern literature to the use of the 3rd house for written examinations (for example, C.C. Zain locates “thoughts, studies and writing” in the horary chart’s 3rd house) but more commonly contemporary horary practitioners tend to look to the 9th and 10th houses for answers to such questions.

Lee Lehman in The Martial Art of Horary Astrology (2002, p250) notes that the modern emphasis on education was not part of the cultural context of 17th century astrologers. Lehman goes on to say the the 9th house of wisdom and abstract knowledge and the opposite 3rd house of more practical knowledge have significance in matters of education. She adds that Lilly’s horary about attaining the Philosopher’s Stone implicates the 10th house as a signifier of the result of years of study and learning.

Christopher Warnock on his website gives an example of the horary question, “Will I pass my finals and graduate from college?” asked in Tel Aviv on 20 June 2003 at 12:21 PM. Virgo rises and Taurus occupies the 9th cusp. Warnock states that Venus, as ruler of the 9th house, signifies higher education, the university and the pending final exams (which are part of university education). Because Asc-ruler Mercury applies to soon conjoin 9th ruler Venus, he delineates that the querent will pass the exam and graduate. Mercury in this chart also rules the Gemini 10th house and thus has the added significance of honors and success.

Nina Gryphon in her website give the example of a horary about whether her husband would pass an exam. She uses the Aquarius 7th house as her husband and argues that because 7th ruler Saturn occupies the Libra radical 3rd (her husband’s 9th) and occupies Libra, its sign of exaltation, that her husband would do well on the exam. She interprets the Retrograde status of Saturn as meaning that her husband will remember the material during the exam. She does not consider whether the Moon or the rulers of her husband’s 9th or 10th (radical 3rd and 4th) houses will aspect his ruler Saturn. Her main argument seems to be that because Saturn rules her husband (Aquarius 7th cusp) and is the exalted ruler of his 9th (the radical 3rd) of higher education, he is bound to do well on the exam.

John Frawley in his Horary Textbook (2014) also identifies the 9th and 10th houses as important in questions about education. In Frawley’s view (p258) the 10th house shows the profit from the knowledge gained through 9th house studies and learning. Frawley then equates the exam results with the profit from study and argues that success on an academic exam is a 10th house matter. Nonetheless, states Frawley, the ruler of the 9th house must be in good enough condition for the querent to pass an exam because the 9th indicates the querent’s level of knowedge of the subject matter.

To summarize commonly used house significations in this type of question are:

1st house: the querent.

3rd house: written documents, primary or ‘hands-on’ education and its attendant examinations.

9th house: universities, higher education, abstract knowledge, studies and learning, exams as part of the advanced education learning process.

10th: honors, success of a venture, judges and their judgments, profit from 9th house knowledge (hence success in an exam), the result of years of study and learning.

In searching the internet I found the following interesting examination question posted in 1995 by astrologer Andrew J. Bevan, QHP, DMS Astrology. Mr. Bevan attempts to answer the query, “Will I pass my physiotherapy exam?”, asked at 15.30 GMT, 8 June 1995 in Oslo, 59N55, 10E43. Here is the chart with Regiomontanus houses and Egyptian terms/bounds. (Bevan writes that the chart was cast on a Venus day during a Mercury hour, which would make the date June 9th rather than June 8th. Because the chart he posted is from June 8th and the text reads June 8th, I will work with the June 8th chart rather than the June 9th chart which matches Bevin’s comments about the day and hour lord. It is possible that he posted the wrong chart and we should be studying the June 9th chart instead. The main difference between the two charts is that on Friday June 9th the Moon would have been at 29 Libra, the other planets have moved only slightly.)

Will I pass my physiotherapy exam? Chart cast for Thursday 8 June 1995 on a Jupiter day during a Mars hour.

The question is asked on a Jupiter day during a Mars hour. Mars also rules the Ascendant and thus signifies the querent as well as 6th house health-related matters. The very early Ascendant is a consideration before judgment.

Higher learning is shown by the Regiomontanus 9th house, which has Gemini on the cusp and Cancer intercepted within. Thus, Mercury signifies her studies and the Moon may act as a co-ruler.

The success of her studies, as reflected in her exam grade, will be shown by the 10th house which has Leo on the cusp. Mars (the querent) in Virgo lies in the 10th Regiomontanus house (honors, success) and in the 11th Whole Sign (hopes and wishes) from the Ascendant. Bevan also notes that the 10th house signifies judges (CA p55) and their judgment in court cases, and in many ways an exam is like presenting your evidence to a judge to see whether you are found sufficiently knowledgeable or not to pass the course.

The Moon, a co-ruler of the querent and ruler of Cancer intercepted in the 9th, is applying to trine the Sun, ruler of the 10th of success on exams and a general ruler of honors and recognition — an indication that she will pass the exam. In addition, Mars (querent) and Mercury (9th ruler) are mutually applying to a square with Mars in a domicile of Mercury. According to Bevan, the querent “was examined on the subjects of hip and hand and passed the examination with perfection.”


Here’s another example I found online. The querent asks whether his brother will pass an important exam, which apparently has to do with his career. In this case the 10th house is especially significant because the 10th can signify both career advancement and success on an exam. The question was asked in Karachi, Pakistan, on 17 May 2009 at 12:15 pm. Here is the chart with Regiomontanus houses and Egyptian terms.

Will my brother pass the exam? Asked on a Sun day during a Jupiter hour.

The brother is indicated by the Libra 3rd cusp, ruled by Venus which is in the sign of her detriment in the 8th house and afflicted by Mars, the out-of-sect malefic, so the brother is not in great shape in this question.

To judge the brother’s performance on the exam we must look at the brother’s 9th and 10th houses, which are the radical 11th and 12th, ruled by Mercury and the Moon respectively.

The Moon, ruler of the brother’s 10th, has dignity only by face and is about to square the Sun in the radical 10th from Aquarius, the sign of the sun’s detriment. This is an argument that the brother will fail the exam.

Mercury rules the brother’s 9th of higher education, is peregrine (without essential dignity) and is combust the Sun and applying to the Sun, thus increasing in combustion. This is another argument that the brother will not pass the exam because his knowledge is not sufficient.

The outcome was that the brother did not pass the exam, which was a requirement for the job he was seeking, and therefore gave up on pursuing that job.


In the next post I plan to consider a recent horary about passing an examination from the point of view of Evangeline Adams “new horary” method.
