Aspect-Dignity Interaction

Definition

This is the principle that how strong a planet is in its own right changes how you read its aspects. Two planets forming the same geometric aspect — say, a square at the same orb — can mean quite different things depending on each planet's essential dignity, its standing by sign. Strong dignity (domicile, exaltation, triplicity, bound, or face) lets a planet deliver its significations cleanly through the aspect; weak dignity — detriment, fall, or being peregrine (with no dignity anywhere) — weakens or distorts that delivery. The geometry holds; the planets' condition shifts.

In Tradition

In Hellenistic and traditional Western practice, the dignity of the planets joined by an aspect governs how reliable that aspect is. Lilly's Christian Astrology I (1647) treats a well-dignified planet's aspects as more dependable in producing favourable or stable outcomes, while a weak or peregrine planet's aspects — sextile, trine, square, or opposition alike — read as less reliable, often partial, distorted, or short-lived even from the easier ones. Bonatti and the Arabic-Persian tradition keep the axis.

In Practice

When weighing an aspect, you first check the essential dignity of each joined planet at its degree. A trine between two well-dignified planets reads as the strongest favourable signature; a trine between two peregrine planets, still favourable in shape, reads as weaker and more dependent on circumstance. A hard aspect (square or opposition) between well-dignified planets reads as productive challenge — the planet has the working capacity to turn the aspect's tension into a usable outcome — whereas the same aspect between weak planets reads as more obstructive, since neither planet has the resource to handle the friction. In Lilly's horary practice — astrology that answers a question — the dignity of the significators counts as much as the aspect type when judging whether the matter asked about comes through. Reception relationships, mutual or mixed, add to the picture: a peregrine planet aspected by a planet that rules its sign or exaltation gains support beyond its bare dignity score.

Historical Origin

The synthesis of dignity-state and aspect-condition runs through the whole Hellenistic-Arabic-medieval-Latin chain. Bonatti's Liber Astronomiae (13th-century medieval Latin, public domain) treats each planet's condition as the governing modifier of an aspect-reading. Lilly's Christian Astrology I (1647, public domain) gives the canonical English horary statement of it: a planet's dignity-strength governs whether its aspect "prevails" in producing what it signifies.
