The Four Elements

Rooted in the philosophy of Empedocles and refined by Aristotle into pairs of qualities — hot/cold, wet/dry — the four elements (Fire, Earth, Air, Water) are one of the two master axes of Western astrology. Each element draws three signs into a triplicity: a trio spaced 120° apart on the wheel, sharing the same fundamental nature while expressing it through three distinct rhythms. The other axis, modality (Cardinal, Fixed, Mutable), tells you how that nature moves; the element tells you what it is made of. Together, these two independent axes account for all twelve signs without overlap or gap. Within each triplicity, the active (yang) signs radiate energy outward, while the receptive (yin) signs draw it inward — an energetic direction, not a hierarchy.
