Gemini (♊) — Mutable Air, The Communicator

Gemini spans 60-90 degrees as the mutable air sign, ruled by Mercury. The Twins (Castor and Pollux) symbolize the sign's essential duality — the capacity to hold two perspectives simultaneously and translate between them. In the Tetrabiblos, Ptolemy assigns Gemini a hot and moist temperament, linking it to the sanguine humor and the faculty of speech. Cafe Astrology emphasizes Gemini's role as the zodiac's communicator and information-gatherer, driven by intellectual curiosity and the mutable modality's restless adaptability.
