Triplicity

Triplicity is a mid-level essential dignity based on elemental rulership. The zodiac's twelve signs are grouped into four triplicities (fire, earth, air, water), and specific planets rule each element, with different rulers for day and night charts. Think of it like knowing people throughout an entire neighborhood: you may not own the house, but you have friends on every block. In Lilly's table, the Sun and Jupiter rule fire, Venus and the Moon rule earth, Saturn and Mercury rule air, and Mars rules water by day and night. In the Dorothean table, water is ruled by Venus by day and Mars by night, with the Moon participating. A planet with active triplicity dignity has a comfortable, cooperative relationship with its environment, scoring +3. It is weaker than domicile or exaltation but still provides meaningful support.
