Horary's vocabulary is largely Latin and Arabic in origin, and much of it entered English untranslated. This glossary collects the terms you may meet in a horary reading — not only with what they mean, but with what they actually say in a chart.
Core concepts
- Querent
- The person asking. Represented by the 1st house of the chart and the ruler of that house.
- Quesited
- The thing or person asked about. Represented by the house the matter belongs to and the ruler of that house.
- Significator
- The planet standing for one side. Every horary chart has at least two; the Moon is always a third.
- Radical chart
- A chart that genuinely represents the question and is fit to be read. The considerations before judgment are the test of radicality.
- Ascendant
- The sign and degree rising on the eastern horizon at the moment of the question. It begins the 1st house and sets the whole house structure.
- Cusp
- The degree at which a house begins. The ruler of the sign on the cusp is the ruler of that house.
Aspects and motion
- Conjunction (0°)
- Two planets at the same degree. Union, entanglement. With a benefic it strengthens; with a malefic it spoils.
- Sextile (60°)
- Harmonious but requiring effort. The opportunity is there; it has to be taken.
- Square (90°)
- An aspect of friction. The event happens, but at a cost — obstruction, tension, strain.
- Trine (120°)
- The easiest aspect. The event flows of its own accord. One of the strongest positive testimonies in horary.
- Opposition (180°)
- Facing off. The event occurs, but with a conflict, a parting, or regret.
- Orb
- The degree of tolerance within which an aspect counts before it is exact. Classical horary assigns orb by planet (its moiety), not by aspect.
- Applying
- The faster planet is moving towards the slower and the aspect has not yet perfected. Classical reading: the event lies in the future. This is the basic condition for a positive answer in horary.
- Separating
- The aspect has already perfected and the planets are moving apart. The event is in the past, or its window has closed.
- Perfection
- The moment the aspect becomes exact. Timing is calculated from the degrees remaining until perfection.
- Retrograde
- A planet appearing to move backwards. Withdrawal, a change of mind, delay — and, where lost things are concerned, return.
- Station
- The moment a planet appears to stand still before changing direction. Classically the weakest and most irresolute condition.
Essential dignities — the strength of a significator
The sign a planet occupies describes how freely it can act. Classical astrology measures this on a five-step scale.
- Domicile (rulership)
- The planet is in its own sign. The strongest position: at home, resources to hand, able to do as it wishes.
- Exaltation
- The sign where a planet is honoured. Strong, but somewhat overstated — a guest seated at the head of the table.
- Triplicity
- A weaker, element-based dignity. The planet is comfortable but not decisive.
- Term (bound)
- A fine dignity resting on the degree within the sign. Small, but it counts as testimony.
- Face (decan)
- The weakest dignity. In the classical phrase, standing at one's own front door — not fallen, but not strong either.
- Detriment
- The planet is opposite the sign it rules. It is in foreign territory: unwilling, uneasy, ineffective.
- Fall
- The planet is opposite its exaltation. Counted weaker still than detriment — discredited, insecure, fragile.
- Peregrine
- The planet holds no dignity at all. Neither strong nor weak: directionless, unowned, adrift. In horary it signals irresolution; in questions of lost property the thief's significator is classically sought among the peregrine planets.
Proximity to the Sun
- Combustion
- The planet is within 8 degrees of the Sun. Classically it cannot see, be heard, or function: its power has been taken from it. One of horary's heaviest negative testimonies.
- Under the beams
- Within 17 degrees of the Sun but beyond 8. Weakening, though not as severely as combustion — being left in shadow.
- Cazimi
- The planet is at the very heart of the Sun, within 17 minutes of arc. The exact opposite of combustion: the tradition counts it among the strongest positions there is — seated on the king's throne. It is rare, and worth noting when it occurs.
Techniques between significators
- Translation of light
- A third and faster planet — often the Moon — separates from one significator and applies to the other, bridging them. In practice: the event happens through an intermediary. Someone who steps in, a coincidence, a piece of news.
- Collection of light
- Both significators apply to a slower third planet, which gathers them together. Usually a third party in a position of authority: a manager, a judge, an elder of the family.
- Prohibition
- Another planet cuts in before the aspect between the significators can perfect, and severs the connection. An obstacle from outside.
- Refranation
- With the aspect about to perfect, one significator turns retrograde and withdraws. A change of heart from inside: the decision reversed at the last moment, the contract cancelled.
- Frustration
- While one significator applies to the other, a third planet reaches the target first and spoils the matter. A relative of prohibition; the difference is that the spoiler arrives first.
- Besiegement
- A planet is caught between the two malefics, Mars and Saturn. Pressure from both sides: no way out and no room to move.
- Reception
- One planet rules the sign the other occupies, and so 'receives' it. A host welcoming a guest: even a hard aspect softens where there is reception.
- Mutual reception
- Two planets each in the other's sign. Classically a very strong positive testimony: the parties can stand in for each other and lend each other support. It can rescue even badly placed significators.
House and chart terms
- Regiomontanus
- The standard house system of classical horary, named after the 15th-century astronomer Johannes Müller (Regiomontanus). Lilly used it; so does Astrum.
- Angular houses: 1, 4, 7, 10
- The strongest houses of the chart. A planet here is effective and matters move quickly. In timing they point to months.
- Succedent houses: 2, 5, 8, 11
- Middling in strength. The event happens but takes time. In timing, weeks.
- Cadent houses: 3, 6, 9, 12
- The weakest houses. A planet here has diffuse effect. In timing, days.
- Derived house
- When the question concerns someone else's affairs the chart is turned: that person's house becomes the new 1st, and counting continues from there. Mother's car is the 2nd from the 4th — the 5th house.
- Void of course
- The Moon will complete no major aspect before leaving its sign. Classical reading: nothing at all is moving in this matter.
- Via Combusta
- The 'burnt road', from 15° Libra to 15° Scorpio. With the Moon here, the answer to the question is classically counted unreliable: a zone of emotional turbulence.
- Lunar nodes
- The two points where the Moon's orbit crosses the ecliptic. The North Node increases, the South Node diminishes. They are not significators; they lend a quality to wherever they fall.
- Antiscia
- A planet's reflection across the solstice axis. Hidden connections: a relationship can be found through antiscia where no aspect is visible. An advanced technique.
Note: Most of these terms appear inside the readings Astrum produces — but never on their own. If a reading says “the significator is peregrine,” it says immediately afterwards what that means for this particular question. Using a term without explaining it does not inform the reader; it impresses them.
