Western astrology
The sky of the Greeks and the moderns: signs, houses, planets, aspects and fixed stars — the full grammar of the Western chart.
Zodiac Signs
Explore all twelve signs of the tropical zodiac — their elements, modalities, ruling planets, and the archetypes they carry from Aries to Pisces.
The Twelve Houses
The twelve astrological houses map every sphere of human life — from self and body to career, love, and beyond. Discover what each house reveals in your chart.
Planets
In astrology, the planets are the core actors of your chart — each one a distinct drive, need, or force shaping how you move through life.
Major Asteroids
The major asteroids bring feminine archetypes and mythic depth to any natal chart — discover what Ceres, Pallas, Juno, Vesta, and Chiron reveal.
Fixed Stars
Discover the fixed stars of astrology: ancient luminous points that sharpen any natal chart with myth, fate, and stellar precision.
Aspects
Aspects are the angular distances between planets on the ecliptic — the living geometry of a chart, revealing where energies flow, tension builds, and growth demands attention.
Chart Angles
The four angles — Ascendant, Midheaven, Descendant, and Imum Coeli — are the most time-sensitive and structurally vital points in any natal chart.
The Four Elements
The four elements — Fire, Earth, Air, and Water — are the foundational energetic layer of Western astrology, grouping the twelve signs into triplicities of shared nature.
Modalities
The three modalities — cardinal, fixed, and mutable — describe how each zodiac sign acts. Cross them with four elements and you define all twelve signs exactly.
