Essential Dignity

Essential dignity is a fivefold scheme for rating a planet’s condition by the degree it occupies: domicile, exaltation, triplicity, bound and face. The five are nested, from the whole sign down to a single degree, and a planet may hold several at once or none at all.

The scheme is old, and it is not uniformly secure. One of its five parts is undisputed across the entire tradition, one is disputed only in its provenance, and one is contested to the point where publishing a single table under a single name would be misleading. This entry says which is which.

Detriment is derived: it is the sign opposite each domicile, so there is no second place for the same fact to be wrong.

No source disagrees. The scheme runs unchanged from the Hellenistic period through Lilly 1 bk. I2 bk. I, and the modern reassignment of Scorpio, Aquarius and Pisces to the outer planets after 1781, 1846 and 1930 is a separate system layered over this one. Most contemporary practice cites both; a traditional-revival school uses only the seven 3.

Detriment is the sign opposite each domicile. This site derives it from the domicile table, so there is no second place for the same fact to be wrong.

The two columns have different provenances. Ptolemy gives the exaltation signs, with a physical rationale for each. The degrees are not in Ptolemy. They reach Hellenistic astrology from the Mesopotamian material, independently of him, and are standardised much later. This makes them at once the oldest and the least Ptolemaic element of the dignity system.

The two halves of that table have different provenances and are usually presented as though they had one.

Correction

Commonly saidThe exaltation degrees come from Ptolemy.

Ptolemy gives exaltation signs, with a physical rationale for each, and no degrees at all 1 bk. I. The degree numbers descend from a separate and older stream: they reach Hellenistic astrology from the Mesopotamian celestial material independently of Ptolemy, and were standardised much later 4.

The consequence deserves plain statement. The exaltation degrees are simultaneously the oldest and the least Ptolemaic element of the dignity system. A reader who has been told they are Ptolemy’s has been told something that makes them younger and less interesting than they are.

Mercury is the only planet exalted in a sign it already rules; every other planet is exalted as a guest, and no source resolves the anomaly, so this entry leaves it unresolved. And the exaltations assigned to the lunar nodes are a medieval Perso-Arabic addition, absent from Ptolemy and Dorotheus and rejected by some later traditionalists. The Vedic node scheme is a different system and is out of scope; it is named here only to keep the two from being run together.

Triplicity

This is the Dorothean scheme: three rulers per triplicity assigned by sect, with a participating ruler alongside the day and night lords 5 bk. I. The same arrangement is in Valens, Paulus, Rhetorius and the Arabic tradition, and it is this site’s default.

Ptolemy differs substantially. He drops the participating ruler as an independent category throughout, and for water he says the triangle falls to the only remaining planet. That is where the transmission splits.

  • Dorothean. The mainstream Hellenistic assignment, shared by Valens, Paulus, Rhetorius and the Arabic tradition.
  • Ptolemy, as received through Lilly. Mars rules water both by day and by night. This is what nearly all modern software ships under the label 'Ptolemaic triplicities'.
  • Ptolemy, on a modern re-reading of the Greek. Venus by day and the Moon by night, with Mars participating regardless of sect: essentially the Dorothean assignment with Mars promoted. On this reading the seventeenth-century simplification is the source of the received table.

Contested

At issueWho rules the water triplicity?

Three positions, each with a holder.

Dorotheus and the Hellenistic mainstream give Venus by day, Mars by night, and the Moon participating 5 bk. I.

Lilly, and the received table that descends from him, gives Mars by day and by night, with no participating ruler 2 bk. I. This is what nearly all modern software ships under the label “Ptolemaic triplicities”.

A close reading of Ptolemy’s Greek gives Venus by day and the Moon by night with Mars participating regardless of sect, that is, essentially the Dorothean assignment with Mars promoted, and holds that the received table is a seventeenth-century simplification 1 bk. I.

The dispute is live among competent modern traditionalists. This site ships all three side by side, because the third position is a modern scholarly re-reading of a seventeenth-century reading of a second-century text, and flattening that into one table would conceal the most interesting thing about it.

Bounds

The bounds, Greek horia, divide each sign into five unequal segments ruled by the five non-luminaries. Two tables circulate under two names, and they are in very different evidentiary condition.

Every row sums to exactly 30 degrees and contains each of the five non-luminaries exactly once. Both invariants are asserted by a unit test against this table.

Textually secure across all twelve signs, including the four commonly flagged as contested. Ptolemy tabulates the same values while objecting to their rationale, which incidentally confirms the content: he asks why the Egyptians gave first place in Aquarius to Mercury rather than to Saturn, so their table had Mercury first in Aquarius, as this one does 1 bk. I. This is the scheme the Hellenistic corpus overwhelmingly uses, and it is this site’s default 3.

Every row sums to exactly thirty degrees and contains each of the five non-luminaries exactly once. Both invariants are asserted by a unit test against the same table this page renders, so a mistyped digit is a failed build rather than a wrong number on a page.

One wrinkle, a production error: Renaissance editions descending from a 1553 Latin retranslation carry a compositor’s slip in the Capricorn row, and some copies reverse the Jupiter and Saturn order in Taurus. A reader who meets those numbers in an old printing is looking at a typesetting fault that was noticed and corrected at the time.

Cells marked "not transcribed" are not gaps in the tradition. They are rows this site has not checked against a printing, and inventing them to make the table look complete would defeat the purpose of publishing it.

  • How wide is the third bound of Virgo? Not stated: The text renders the Virgo widths as Mercury 7, Venus 6, Jupiter blank, Saturn 6, Mars 6. The Jupiter figure is missing. 5, by arithmetic: Five is the only width that brings the row to 30. It is what this site carries, marked as reconstructed.
  • Which planet holds the last bound of Gemini? Mars 20-26, Saturn 26-30: Every English translation and both modern critical Greek editions. Saturn 21-25, Mars 25-30: Lilly, following Cardan and Junctinus. This is the version most modern astrology software ships under the name Ptolemaic.
  • Does the first bound of Leo belong to Jupiter or to Saturn? Jupiter: The Greek line. Robbins prints Jupiter as the first term of Leo. The report that the oldest manuscript of the Paraphrase carries Jupiter and Saturn together, with Jupiter primary, is not confirmed from any source this site holds. Saturn: The Arabic transmission line moves Jupiter to the fifth bound, which puts a benefic last, against the rule Ptolemy states elsewhere that malefics belong at the end of a sign.
  • In what order and at what widths do Mars and Saturn take the end of Taurus? Saturn then Mars: The Greek line, following a tenth-century manuscript. The standard English translation flags this as the one place that manuscript disagrees with the Camerarius printing. Reversed, with different widths: The Arabic transmission line reverses both the order and the degree counts.
  • Does Saturn or Mars hold the fourth bound of Capricorn? Saturn fourth, Mars fifth: The standard English translation, following its tenth-century manuscript. Carried here. Mars fourth, Saturn fifth: Camerarius, Lilly and the Greek critical editions reverse it. The degree widths of Lilly's row are not transcribed here because they were not checked against a printing.

Ptolemy presents this table as recovered from an ancient and damaged manuscript and says so directly: the book was lengthy, excessive in demonstration, and in a state that made it hard to read, so that he could barely gain an idea of its general purport 1 bk. I. He did not design it and did not claim to have fully understood it. No two lines of transmission agree, and the critical edition of the Greek carries an apparatus of variants rather than a settled text 6.

Contested

At issueWhat are the last two bounds of Gemini in the Ptolemaic table?

Every English translation and both modern critical Greek editions give Mars from 20 to 26 degrees and Saturn from 26 to 30 1 bk. I6.

Lilly gives Saturn from 21 to 25 and Mars from 25 to 30, with different widths for the Jupiter and Mars bounds as well; his version descends from two sixteenth-century editions he owned 2 bk. I.

Nearly all modern astrology software ships Lilly’s version while labelling it “Ptolemaic”. That is the cleanest documented split in the whole transmission, and it is the reason this site publishes the witnesses side by side.

Gap in the evidence

The third bound of Virgo in the Ptolemaic table is not attested. The text gives the widths as Mercury 7, Venus 6, Jupiter blank, Saturn 6, Mars 6. Five is the only value that brings the row to thirty, and five is what this site carries, marked as reconstructed. It must be checked against a printed critical edition before it is presented as anything else.

Four further cells are disputed between the Greek and the Arabic lines of transmission: the first bound of Leo, the last two of Taurus, the last two of Capricorn, and several degree counts in Gemini and Scorpio. Where this site has not checked a witness against a printing, the cell reads “not transcribed” and stays that way until a printing has been checked.

Given all of that, the recommendation this site follows is to default to the Egyptian bounds, which are textually secure and are what the corpus uses, and to present the Ptolemaic table behind the transmission problem. The transmission problem is more interesting than the table.

Faces

The faces divide each sign into three ten-degree segments, assigned in Chaldean order beginning with Mars at zero Aries and running straight through the sign boundaries without resetting. Because thirty-six is not divisible by seven the cycle does not close, so the last face of Pisces and the first face of Aries are both Mars, by construction.

This site generates the faces from the rule, and the generated result matches the received table exactly. The scheme is not Ptolemy’s: his own chapter on faces describes an aspect relation between a sign and the luminaries, a different concept. The thirty-six-face table is the Egyptian-derived Hellenistic vulgate that Dorotheus and Lilly use 5 bk. I2 bk. I, and it is a different lineage again from the Egyptian decans as star-clocks and from the decan images of the later magical literature. Running the three together is endemic in popular writing.

Scoring

Lilly assigns point values to the five dignities and to detriment, fall and peregrination, and sums them. Hellenistic authors do not do this. Wherever a dignity score appears on this site it carries the date 1647 and the name Lilly, because presenting a score implies a quantitative doctrine that the ancient sources do not have 2 bk. I.
