Horary astrology, an ancient segment of horoscopic astrology, enables astrologers to respond to questions by creating a horoscope for the precise moment the question is received and comprehended. Among horary astrologers, there’s a debate over whether to use the location of the querent—the individual posing the question—or the astrologer’s location. Typically, both are in the same locale, but with many astrologers now operating online or via phone, scenarios arise where, for instance, a querent in Australia might email a question to an astrologer in Europe, resulting in a significantly different horoscope. While many European astrologers opt for the querent’s location, traditional English schools have prominent advocates for using the astrologer’s location. Answers to horary questions can range from a straightforward yes or no to more nuanced insights that reveal, for example, the questioner’s motives, others’ intentions involved in the matter, and the choices available.

Despite their name, the Arabic Parts were not originally created by Arab astrologers; rather, they were developed by the Persian astrologer al-Qabisi in the 10th century. However, the Arabic-speaking world played a crucial role in preserving and disseminating al-Qabisi’s works and those of other Persian astrologers to the Western world. This is why these constructs are commonly referred to as the “Arabic Parts” of astrology.





In horary astrology, a distinct set of rules guides the interpretation of charts. The moon’s position and aspects take precedence, while the querent, or person asking the question, is represented by the ruler of the sign on the first house cusp. Planetary aspects to the house cusps are highly significant, with particular emphasis on the rulers of those houses. Additional factors such as the lunar nodes, planetary antiscia, and Arabic parts are also considered. When interpreting a horary chart, the subject of the question is assigned to a specific house, such as the sixth house for inquiries about lost pets. For example, if the sixth house cusp falls in Libra, Venus becomes the significator of the lost dog. The condition of Venus in the chart, including its dignity and aspects, provides insights into the animal’s whereabouts.

Classical Considerations

First, determine the exact moment you either posed the question or received it from someone else, along with your location at that time. These details will form the basis of your calculations. Proceed to calculate your chart. Before moving forward with the judgement, there are several fundamental aspects to consider:

Is the Ascendant less than 3 degrees or greater than 27 degrees? If the Ascendant is less than 3 degrees, it may be premature to reach a conclusion; if it is greater than 27 degrees, it may be too late. However, matters concerning new beginnings might still be feasible with an Ascendant under 3 degrees. This does not hold if the querent’s Ascendant is less than 3 degrees or exceeds 27 degrees.

Is the Moon located in Via Combusta? Via Combusta spans from 15º Libra to 15º Scorpio and is considered a malefic and unpredictable influence.

Is the Moon Void of Course? The Moon is considered void of course when it does not form any major aspects before exiting its current zodiac sign. During such times, activities tend not to proceed smoothly. Lilly states that the Moon is void of course if it is not within the orb of applying to a major aspect prior to leaving its sign. However, Lilly concedes that in Cancer, Taurus, Sagittarius, or Pisces, a void of course Moon may still be effective.”

Is the Moon positioned in the final degrees? It may be precarious to evaluate a chart when the Moon occupies the terminal degrees of a sign, particularly Gemini, Scorpio, and Capricorn.”

Is Saturn positioned in the Seventh House? As an astrologer, your ability to judge may be limited or constrained, except if you are the one seeking the answer.”

When the astrologer themselves is the querent, is Saturn positioned in the First House? As an astrologer, your ability to judge may be impaired or limited.

Firstly, determine the ruling planets of the querent and the question. The querent is invariably co-ruled by the Moon, as well as by the ruler of the Ascendant, the Almuten(s) of the Ascendant, and any planetary rulers of the first house. Next, identify the natural ruler for the issue and ascertain which houses are significant in this matter. It may be necessary to rotate the chart; for instance, if inquiring about a partner’s career, instead of examining the tenth house (representing your own career), you would consider the seventh house (representing your partner) as their first house and count ten houses from there. Thus, the seventh house plus ten leads to the fourth house, indicating that matters concerning the partner’s career are governed by the fourth house.”

Rulership of the Planets

Planets are deemed to be under the sunbeams when they reside in the same sign as the Sun and are within 17 degrees. Their influence is diminished in this position. A planet becomes combust when it is in conjunction with the Sun, defined by an orb of 8 degrees, which also weakens its effect. Conversely, planets are considered cazimi when they are within 0 degrees and 17 minutes of the Sun, a position that enhances their strength, unlike being combust. However, the Moon is an exception; it is deemed malefic when in this position as it corresponds to a New Moon.”

Sun: Represents self-expression, vitality, authority, masculine energy, employers, power, ego, and officials.
Moon: Symbolizes emotions, intuition, cycles, home life, nurturing, the public, lost items, short journeys, changes, and the mother.
Mercury: Governs thought processes, communication, speech, business dealings, transportation, contracts, neighbors, youth, students, and office work.
Venus (The Lesser Benefic): Influences love, creativity, beauty, social interactions, gifts, finances, marriage, young women, mothers, spouses, pleasures, and luxury items.
Mars (The Lesser Malefic): Drives action, energy, assertiveness, sexual energy, accidents, conflict, aggression, weapons, and injuries.
Jupiter (The Greater Benefic): Brings luck, growth, opportunities, expansion, abundance, excess, speculation, higher education, long-distance travel, foresight, foreigners, the affluent, and professionals.
Saturn (The Greater Malefic): Imposes duties, responsibilities, challenges, lessons, ambition, discipline, restrictions, delays, poverty, obstacles, paternal figures, mortality, and limitations.
Pars Fortuna (Part of Fortune): Not a planet but an Arabic Part, it signifies income, possessions, wealth, and financial prosperity.

Fixed Stars

Fixed stars can exert influence on an astrology chart when a planet is in conjunction with them, typically within an orb of 1 degree.

Here are some notable fixed stars and their associated influences:

– Caput Algol at 26º10′ Taurus: Associated with failure, difficulties, disaster, and death.

The Arabic Parts

The Arabic Parts, also known as lots, are derived by adding and subtracting the positions of planets and other chart features. These were extensively utilized by Arab astrologers during the 8th and 9th centuries, who acquired this knowledge from Babylonian, Egyptian, and Greek astrological traditions. For instance, the Pars Fortuna or Part of Fortune is calculated during the day as Ascendant plus Moon minus Sun, and during the night as Ascendant plus Sun minus Moon. Ancient astrologers held the belief that the Ascendant and the Part of Fortune were pivotal elements of the chart, corresponding to the rising of the Sun and Moon, respectively.

Note: ‘C’ denotes the cusp of the specified astrological house; ‘R’ signifies the ruling planet of the mentioned house; ‘MC’ stands for midheaven in the chart being used; ‘SN’ represents the south node; ‘NN’ indicates the north node; ‘PF’ refers to the Part of Fortune.”

Further Lots

The discovery of over two dozen lots sourced from Egyptian origins should put to rest the misconception that lots are exclusively Arabic. Many of these lots originate from a text called the Panaretos, attributed to Hermes Trismegistus. While Hermes Trismegistus is a legendary figure lacking historical evidence, any works attributed to him prior to the Middle Ages can be attributed to Hellenistic Egyptian sources or even earlier. The Lot of Fortune, for example, was attributed to Nechepso and Petosiris, a pharaoh and his priest.

Among the lots assigned to planets, the Lot of Fortune was attributed to the Moon, while the Lot of Spirit was linked to the Sun. The Lot of Spirit holds significant importance, second only to the Lot of Fortune. Its formula is straightforward: it mirrors the Lot of Fortune, but with the positions of the Sun and Moon in the formula reversed. Therefore, the formula for the Lot of Spirit during the day is the same as that of the Lot of Fortune during the night, and vice versa. The following formulas should illustrate this point clearly.

Lot of Fortune
Day Births: Fortune = Ascendant + Moon – Sun
Night Births: Fortune = Ascendant + Sun – Moon

Lot of Spirit
Day Births: Spirit = Ascendant + Sun – Moon
Night Births: Spirit = Ascendant + Moon – Sun

For individuals born at night, many have inadvertently been using the Lot of Spirit instead of the Lot of Fortune due to common software and computer services computing it incorrectly. Unlike the physical-plane-based Lot of Fortune, the Lot of Spirit carries strong psychological and spiritual connotations. It pertains to the nature of one’s will and intentions, rather than solely focusing on external events. Additionally, it holds significance in career matters, reflecting more on the individual’s statement about their place in the world. Furthermore, like the Lot of Fortune, the Lot of Spirit also relates to illness, but it seems to address the spiritual underpinnings of illness rather than just the physical aspects. Unlike the Lot of Fortune, the Lot of Spirit isn’t typically used as a first house marker.

The other planets also possess lots, many of which are derived in part from the Lots of Fortune and Spirit.

In the following notation:
– PF represents the Lot of Fortune
– PS represents the Lot of Spirit

Mercury, Lot of Necessity:
Day: Lot = Ascendant + Lot of Fortune – Mercury
Night: Lot = Ascendant + Mercury – Lot of Fortune

Venus, Lot of Eros:
Day: Lot = Ascendant + Venus – Lot of Spirit
Night: Lot = Ascendant + Lot of Spirit – Venus

Mars, Lot of Courage:
Day: Lot = Ascendant + Lot of Fortune – Mars
Night: Lot = Ascendant + Mars – Lot of Fortune

Jupiter, Lot of Victory:
Day: Lot = Ascendant + Jupiter – Lot of Spirit
Night: Lot = Ascendant + Lot of Spirit – Jupiter

Saturn, Lot of Nemesis:
Day: Lot = Ascendant + Lot of Fortune – Saturn
Night: Lot = Ascendant + Saturn – Lot of Fortune

The next group of lots relates to family issues:

Lot of the Father:
Day: Lot = Ascendant + Saturn – Sun
Night: Lot = Ascendant + Sun – Saturn

If Saturn is within 17 degrees of the Sun, use this formula according to the Greek sources:
Day or Night: Lot = Ascendant + Jupiter – Mars

If Saturn is within 17 degrees of the Sun, Arabic sources uses a different formula:
Day: Lot = Ascendant + Jupiter – Sun
Night: Lot = Ascendant + Sun – Jupiter

Lot of the Mother:
Day: Lot = Ascendant + Moon – Venus
Night: Lot = Ascendant + Venus – Moon

Lot of Siblings:
Day: Lot = Ascendant + Jupiter – Saturn
Night: Lot = Ascendant + Saturn – Jupiter

Not all sources reverse the formula for Siblings at night, and I am inclined to agree with those sources that do not. I suggest that one start with the day formula used for both day and night charts. This may seem inconsistent, but there is a principle underlying my position. In any case, only experimentation will tell.

Lot of Children:
Day: Lot = Ascendant + Saturn – Jupiter
Night: Lot = Ascendant + Jupiter – Saturn

Note that this is the inverse of the Lot of Siblings. Here again, some sources do not reverse the formula at night, and I tentatively agree with those that do not. Obviously, persons born in the daytime have no problem here, but persons born at night will have to experiment.

In addition to the previously mentioned lots, there are other specialized lots mentioned in Greek literature, each with its own intriguing significance. The first being the Lot of Basis. As the name suggests, it seems to represent something fundamental, combining the significations of the Lots of Fortune and Spirit. The formula is as follows:

Lot of Basis:
Day or Night: Lot = Ascendant + Lot of Fortune – Lot of Spirit
or Lot = Ascendant + Lot of Spirit – Lot of Fortune

Here, the order of the formula is determined by the shorter arc between Lot of Fortune and Lot of Spirit. If the arc between them is more than 180 degrees, we use Lot of Spirit – Lot of Fortune, and vice versa. Its position is always below the horizon or exactly on the Ascendant or Descendant because the arc between Lot of Spirit and Lot of Fortune can never exceed 180 degrees. This may relate to its signification, as it is always below the earth like a foundation. Additionally, New Moons and Full Moons hold special significance with this lot, as at the New Moon, all three lots are conjunct the Ascendant, and at the Full Moon, they are all conjunct the Descendant.

Lot of Debt:
Day or Night: Lot = Ascendant + Saturn – Mercury

This lot doesn’t seem to function as a first house indicator. While lore about this lot is not abundant, according to the logic of lots, it could signify financial losses or debt wherever it falls in the chart.

Lot of Theft:
Day: Lot = Saturn – Mars – Mercury
Night: Lot = Saturn – Mercury – Mars

Similar to the Lot of Debt, this lot doesn’t serve as a first house indicator and doesn’t contain the Ascendant as a component. It resembles formulas found in the modern Hamburg School of Alfred Witte.

Lot of Treachery:
Day: Lot = Ascendant + Mars – Sun
Night: Lot = Ascendant + Sun – Mars

There’s limited information available about this lot, sourced from Vettius Valens.

Lot of Exaltation:
Day: Lot = Ascendant + 19 Aries – Sun
Night: Lot = Ascendant + 3 Taurus – Moon

This lot is derived from the exaltation degrees of the Sun and Moon. It’s connected to the births of eminent and famous people.

Lot of Being in a Foreign Land:
Day or Night: Lot = Ascendant + Mars – Saturn

Lot of Accusation:
Day: Lot = Ascendant + Mars – Saturn
Night: Lot = Ascendant + Saturn – Mars

The Lot of Being in a Foreign Land doesn’t switch at night, unlike the Lot of Accusation. The former indicates exile-like circumstances, while the latter suggests areas of life where accusations may occur, potentially leading to failure, dangers, or downfalls.

Lot of the Destroyer:
Day: Lot = Ascendant + Moon – Ruler of Ascendant
Night: Lot = Ascendant + Ruler of Ascendant – Moon

In the formula above, ‘Ru’ stands for the ruler of the Ascendant. This point relates to death, specifically the manner of death. It’s essential to approach the use of this lot with caution, as we have limited systematic information about its application.

In addition to the general lot of children, Vettius Valens provides two other lots specifically related to children: a lot of sons (i.e., male children) and a lot of daughters. These are as follows:

Lot of Sons:
Day or Night: Lot = Ascendant + Mercury – Jupiter

Lot of Daughters:
Day or Night: Lot = Ascendant + Venus – Jupiter
