Peregrine

Peregrine (from Latin peregrinus, "wandering" or "foreign") describes a planet that has no essential dignity in its current position — no domicile, exaltation, triplicity, term, or face rulership. A peregrine planet is like a stranger in a foreign land with no authority or recognized standing. In traditional astrology, peregrine planets are considered unreliable, inconsistent, or prone to deception — their significations cannot be trusted to manifest clearly and faithfully.

In horary astrology, a peregrine significator is a serious debility. William Lilly associated peregrine planets with thieves, vagabonds, and unreliable persons — the idea being that a planet without dignity lacks the standing to act with integrity. If the querent's significator is peregrine, the person may feel directionless or powerless. If the quesited's (asked-about thing's) significator is peregrine, the matter may be difficult to reliably assess or the thing may be hard to find.

In natal astrology, a peregrine planet describes an area of life that lacks consistency and may operate erratically. A peregrine Moon suggests emotional responses that are hard to stabilize. A peregrine Mars may scatter its energy without direction. The remedy, if any, comes from the planet's house and any aspects it receives from well-dignified planets — these can provide borrowed dignity and more reliable expression. Identifying peregrine planets helps set realistic expectations about consistency in those life areas.
