Pisces closes the zodiac: it is the sign of diffuse sensitivity, imagination, an empathy that blurs the boundaries between self and other. A planet in Pisces acts with intuition more than logic, sometimes at the cost of a lack of clear limits.
A Mercury in Pisces, for example, thinks in images and intuitions rather than linear reasoning; this principle applies to any planet found there, not just the Sun.
Element: Water. Modality: Mutable. Ruler (domicile): Jupiter, in the classical seven-planet system. Opposite sign: Virgo. Natural house: 12 (the invisible, withdrawal, what escapes conscious control).
Venus is in exaltation here (around 27°); Mercury, by contrast, is in fall here — Mercurial precision and analysis express themselves poorly, diluted by the sign's logic.
Modern (20th-century) astrology conventionally assigns the co-rulership of Pisces to Neptune — see the Neptune entry for this convention, distinct from the classical dignities.
