The Astrolium essential dignities calculator returns the full Hellenistic dignity table for every classical planet, plus the almuten figuris and the five hyleg points used to compute it. The output covers domicile, exaltation, triplicity, term, decan, detriment, fall, peregrine status, and sect condition. Free, no signup.
Essential dignities are a core tool of traditional and Hellenistic astrology. They measure a planet's condition, how naturally it expresses itself in its current sign, using a five-layer system developed over two thousand years of practice from Ptolemy through the Persian, Arabic, and medieval Western traditions.
Astrolium's essential dignities calculator returns the full Hellenistic dignity table for the seven classical planets and computes the almuten figuris across the five hyleg points (Ascendant, Sun, Moon, prenatal lunation, Lot of Fortune). The tool accepts birth date, time, and place, then scores each planet across domicile (+5), exaltation (+4), triplicity (+3), term (+2), decan (+1), detriment (-5), and fall (-4), using the Dorothean triplicity scheme and Egyptian terms by default. Output flags peregrine planets, day or night sect, and accidental conditions including combust, cazimi, and under-the-beams. The hyleg-by-hyleg score sheet shows why the almuten landed on a particular planet. Practitioners use it to identify a chart's ruling planet in traditional delineation, particularly when the Ascendant ruler is peregrine but another planet stacks dignities. Calculations use Swiss Ephemeris with sub-arcsecond accuracy. Free, no account required.
What the calculator returns
A planet in domicile (ruling its own sign) is like a person at home: comfortable, resourceful, able to act from a position of strength. In exaltation, it is honoured and operating at peak expression. In triplicity, it sits in its elemental family. Term and decan add finer texture.
The table covers all seven classical planets: Sun, Moon, Mercury, Venus, Mars, Jupiter, and Saturn. For each planet you get the sign, the dignities that apply, the dignity score, detriment or fall status, and any planetary conditions (combust, cazimi, under the beams). The almuten table runs the five-hyleg score; sect analysis flags day or night chart and the planets that benefit from sect condition.
How essential dignities work
Each planet receives a dignity score based on where it sits. The standard weighting follows Ptolemy:
- Domicile (own sign): +5
- Exaltation (honoured sign): +4
- Triplicity (elemental ruler): +3
- Term (Egyptian subdivision of the sign): +2
- Decan (10-degree subdivision, Chaldean order): +1
- Detriment (sign opposite domicile): -5
- Fall (sign opposite exaltation): -4
A planet can stack dignities. Mercury at 6 degrees of Virgo holds domicile (Virgo), exaltation (Virgo), triplicity (Virgo earth by day), and the first term (Mercury's own term), totalling 14. That is a textbook dignified Mercury.
A planet with no positive dignity in its sign is peregrine. The calculator flags this explicitly; peregrine planets still function but lean on aspects from dignified planets to deliver their significations cleanly.
Almuten figuris: what it is and how the calculator finds it
The almuten figuris is the chart's ruling planet by dignity weight, computed across the five hyleg points:
- The Ascendant
- The Sun
- The Moon
- The prenatal lunation (the New Moon or Full Moon immediately before birth)
- The Lot of Fortune
For each hyleg point, every planet receives its dignity score in that sign and degree. The five scores are summed across all hyleg points. The planet with the highest total is the almuten figuris.
Persian and medieval astrologers used the almuten figuris as a primary identification of the chart's ruling planet. In some traditions it overrides the Ascendant ruler when the two disagree. The technique gives a more complete picture than the Ascendant alone because it weighs the five most important sensitive points of the chart together.
The calculator returns the full hyleg-by-hyleg score sheet so you can see why the almuten landed on a particular planet, not just the result.
Triplicity ruler and the Dorothean scheme
Triplicity is the third-strongest dignity. Each element has three rulers under the Dorothean scheme used by Dorotheus of Sidon and most Hellenistic practitioners:
- Fire (Aries, Leo, Sagittarius): Sun by day, Jupiter by night, Saturn participating
- Earth (Taurus, Virgo, Capricorn): Venus by day, Moon by night, Mars participating
- Air (Gemini, Libra, Aquarius): Saturn by day, Mercury by night, Jupiter participating
- Water (Cancer, Scorpio, Pisces): Venus by day, Mars by night, Moon participating
Day or night chart is decided by the Sun's house position. Sun above the horizon (houses 7 through 12) is a day chart; below the horizon (houses 1 through 6) is a night chart. The dignity score flips between day and night triplicity rulers accordingly.
A peregrine planet that receives an aspect from its triplicity ruler is partially supported. A planet in its own triplicity reads as broadly capable even without higher dignity.
Reading the dignity table in practice
A planet with multiple dignities, domicile and exaltation for example, is considered very well placed. A planet in detriment or fall requires more effort to express its positive qualities but is rarely simply bad. Mars in Cancer (fall) often shows a person who works harder than a Mars in Aries to get the same Mars-shaped result; the function is intact, the cost is higher.
The almuten figuris is the apex read. When the Ascendant ruler is dignified and matches the almuten, the chart has a single clear ruler. When the two disagree, which is common when the Ascendant ruler is peregrine but another planet stacks dignities across the five hyleg points, the almuten gives the chart's deeper structural ruler.
The dignity table reads sharply against the hellenistic astrology feature and the hellenistic astrology guide. For the Lot of Fortune that feeds the almuten calculation, see the part of fortune calculator. For sect-based analysis, see the sect calculator.
