Pluto Transit
greek: ἐπέμβασις (epembasis) · latin: ingressus
Definition
The passage of transiting Pluto across a degree or aspect-point in the natal chart. Because Pluto's sidereal period is roughly 248 years and its motion sometimes falls under one degree per year, a Pluto transit to a single natal point can extend across one to three calendar years, including multiple retrograde passes — so the contact is read as an extended period rather than a discrete event.
In Tradition
The underlying transit doctrine is well-attested: Crane records the Greek word ἐπέμβασις (epembasis) — 'a stepping upon, a walking upon, and also a walking through' — as the technical noun rendered both 'transit' and 'ingress' in the tradition; the Liber Hermetis editors note the same term in the Latin ingressus. Modern outer-planet practice layers Pluto-specific meanings — Rudhyar's framing of Pluto as 'the planet of the second birth, ruler of the Mysteries' — onto this ancient transit framework.
In Practice
Practitioners watch Pluto by sign and by transit-to-natal contact. Hard contacts (conjunction, square, opposition) to Sun, Moon, Ascendant ruler, or chart-ruler are read as extended periods of pressure to dismantle and rebuild the life-area signified by the natal point — Rudhyar's 'regenerating power.' Because Pluto can station within a degree of an exact contact for several months and pass over the same point three times in a year (direct-retrograde-direct), Pluto transits are tracked across a multi-year arc rather than single dates. Generationally, Pluto's sign placement is shared across cohorts, so practitioners distinguish the personalised house-and-aspect transit from the collective sign passage.
Historical Origin
Transit doctrine is documented from the Hellenistic tradition forward (Greek ἐπέμβασις in Crane's reconstruction; Latin ingressus in Liber Hermetis per Zoller-Project-Hindsight) and is one of the principal predictive techniques across Arabic and modern Western practice. Pluto itself was discovered in 1930 (Tombaugh), so 'Pluto transit' as a specific practitioner concept is a post-1930 Western-modern adaptation — Rudhyar's *The Astrology of Personality* (1936) is one of the earliest substantive astrological framings of Pluto, and the modern transit-interpretation lineage carries it forward.
Etymology
Origin: Greek + modern. Meaning: transit = ἐπέμβασις (epembasis), a stepping upon or walking through; Pluto = Roman name for the Greek Hades, applied to the planet discovered 1930.
