Classification and Hierarchy of Power
"The opposition has maximum nefarious power: total contradiction, separation, or destruction. It is the worst possible aspect. The trine has maximum constructive power: fluid realization, stable success, and abundance."— Astrologia Gallica — Treatise on Aspects, Section 1
BENEFIC ASPECTS (Constructive):
Trine (120°) — MAXIMUM power. Fluid realization, stable success, abundance. The best possible configuration.
Sextile (60°) — INTERMEDIATE power. Opportunities that require cooperation or action to manifest.
Semi-sextile (30°) — MINIMAL power. Light facilitation. Secondary factor only.
---
MALEFIC ASPECTS (Obstructive):
Opposition (180°) — MAXIMUM nefarious power. Total contradiction, separation, or destruction. The worst aspect possible.
Square (90°) — INTERMEDIATE malefic. Rupture, extreme effort, "martial relationship." Can produce achievement through struggle.
Quincunx (150°) — MINIMAL malefic. Lack of connection, discordance, forced adjustment, persistent discomfort.
---
THE CONJUNCTION (0°) — Special case:
Not an aspect but a corporal union. ABSOLUTE power. Quality is variable: if the planets are natural enemies (e.g., Jupiter–Saturn), the one with the better Celestial State dominates. The weaker planet is absorbed by the stronger.

The Square can produce success through fierce struggle when it falls in House X. The Trine can facilitate death or loss when it falls in House VIII. The aspect's final meaning is always determined by the house where it lands — never the aspect alone.
Application vs. Separation: The Most Critical Rule
"Absolute priority to APPLICATIVE aspects (approaching exact degree). They are far more effective for producing real events than separating aspects."— Astrologia Gallica — Aspects, Section 2A
This is the rule most ignored by modern astrologers and most critical for Morin.
Applying aspect: The faster planet is moving toward the exact degree of aspect with the slower planet.
→ Effect: ACTIVE. The event is in process of formation. It WILL manifest.
Separating aspect: The faster planet has passed the exact degree and is moving away.
→ Effect: PAST. The event has already happened or its energy is dissipating.
Partil aspect (exact to the degree): Absolute preeminence over any other simultaneous aspect. When a planet is exactly conjunct, trine, square, or opposite another within the same degree — this overrides all other considerations in timing.
Practical implication: When you see two aspects to the same planet, the applying one tells you what is coming. The separating one tells you what has been. Do not weight them equally.

An applying aspect is a promise. A separating aspect is a memory. Always identify which is which before interpreting.
Determination by Receiving House (Rule 107)
"An aspect is NOT good or bad in the abstract. It undergoes the determination of the house where it falls. A trine falling in House 8 may facilitate a death or loss. A square falling in House 10 may produce success through fierce struggle."— Astrologia Gallica — Rule 107
This is the most commonly violated rule in popular astrology. Rule 107 states that no aspect can
be evaluated in isolation from the house where it terminates.
The Morinian Syntax for any aspect:
*"[Emitting Planet] sends a [Aspect Name] to [Receiving House], determining [Ease/Obstacle] for the affairs of that house, according to the nature of the emitter and its celestial state."*
Example:
Jupiter (great benefic, in good celestial state) sends a trine to House 7 → Determination: easy, abundant realization of 7th house affairs (marriage, partnerships, open enemies).
Mars (lesser malefic, in detriment) sends a trine to House 8 → Despite the trine being benefic, Mars in detriment sending its quality toward House 8 (death, inheritance, debts) still produces difficult 8th house events, though with less violence than a square would.
Key insight: The aspect type modifies the *how* (fluently vs. with struggle). The house destination determines the *what* (which area of life). The planet's Celestial State determines the *quality* (good vs. bad outcome).

Before saying 'this is a good trine' or 'this is a bad square', always ask: trine to WHICH house? square to WHICH house? The house determines the meaning.
Antiscia: The Hidden Aspects
"Planets in the same parallel of declination (reflection on the solsticial axis) act as a hidden conjunction or union of destinies."— Astrologia Gallica — Aspects, Section 2D
Antiscia are often ignored in modern practice but are a real component of Morin's system.
Antiscion: A planet's mirror point across the Cancer/Capricorn axis (the solsticial axis: 0° Cancer / 0° Capricorn).
Calculation: To find a planet's antiscion, subtract its longitude from 30° if in the first half of a sign, or use the reflection formula: the antiscion of a planet at X° of sign A is at (30° − X°) of the mirror sign.
Simple mirror pairs:
- Aries ↔ Virgo
- Taurus ↔ Leo
- Gemini ↔ Cancer
- Libra ↔ Pisces
- Scorpio ↔ Aquarius
- Sagittarius ↔ Capricorn
Effect: When two planets are in antiscion (one planet occupies the other's antiscion point), they act as if in hidden conjunction — their qualities combine and mutually reinforce, regardless of the actual angular distance between them.
Contra-antiscion: The opposite point acts as a hidden opposition.

Antiscia are hidden conjunctions across the solsticial axis. If two planets are in antiscion, their qualities merge even if they appear unconnected by standard aspects.
Exercise 1 of 3
Identify All Applying Aspects in Your Chart
Open your natal chart. List every applying aspect you can find (planets moving toward exact contact). For each one, identify: (1) which planet is emitting, (2) which planet or house cusp is receiving, (3) what type of aspect it is, and (4) its hierarchy (maximum/intermediate/minimal).
In a natal chart, applying aspects show the chart's 'forward momentum' — the energies and life areas that are still actively forming.
Exercise 2 of 3
Apply Rule 107 to Three Aspects
Choose three aspects from your chart. For each one, write the full Morinian sentence: '[Emitting Planet] sends a [Aspect] to [House], determining [Ease/Obstacle] for the affairs of [House description], according to [Planet's celestial state].' Do not interpret the aspect without completing this sentence first.
Remember: a trine to House 8 is not automatically good, and a square to House 10 is not automatically bad. The house changes everything.
Exercise 3 of 3
Find the Most Powerful Aspect in Your Chart
Looking at all aspects in your chart, identify the single most powerful one according to Morinian hierarchy. Consider: (1) Is it applying or separating? (2) Is it partil (exact)? (3) What is the celestial state of the emitting planet? (4) Which house receives it? Explain why you selected it as the most powerful.
A partil applying trine from Jupiter in domicile to House 10 would rank higher than an opposition from Saturn in detriment to House 2, even though the opposition has maximum malefic power.
