What sets Mutable Signs apart
The mutable signs close each season, standing just before the Sun crosses into the next. Only two planets rule them: Mercury has Gemini and Virgo, Jupiter has Sagittarius and Pisces. They are the double-bodied signs, a name sustained by the figures themselves: the Twins, the Centaur-Archer of two natures and the two Fishes. They are also the cadent set, matching the cadent houses.
- Rulers: Mercury (Gemini, Virgo), Jupiter (Sagittarius, Pisces)
- Position: last sign of spring, summer, autumn and winter
- Greek name: bicorporeal, double-bodied
- Double figures: Twins, Archer-Centaur, two Fishes
- Opposite pairs: Gemini with Sagittarius, Virgo with Pisces
