Uranus

Definition

Uranus in astrology is the seventh planet from the Sun, found by William Herschel in 1781 and unknown to Ptolemy and every ancient astrologer. Modern astrologers tie it to originality and freedom and to Aquarius, a sign Ptolemy had given to Saturn. Alan Leo called it the planet of the Will and the astrologer's own planet.

Primary source

In the abstract, Uranus represents the Will aspect of the spirit, its motives and purpose in life … Uranus is said to be the astrologer's planet, because it is connected with Will and magic, or occultism.

Deep Understanding

Hellenistic astrology worked with seven moving lights: the Sun, the Moon and five planets. Herschel's discovery, the first planet found with a telescope, left astrologers with a body that had no place in Ptolemy's scheme and no ancient text to read it by. Its meaning was built in the nineteenth and early twentieth centuries, partly from its myth and partly from observation.

Alan Leo, the Theosophist astrologer, gave it one of its most influential readings. In Esoteric Astrology he calls Uranus the synthetic planet, the image of the fully individualised and self-conscious being, and sets Saturn between Jupiter and Uranus as the individualising planet. In his scheme Uranus, Mercury and Venus together are the triple aspect that represents the Monad. He also doubts that it acts in every chart: unless Uranus is on an angle or in an airy sign, he writes, it is open to question whether its influence can be felt much. He finds its closest affinity with Aquarius and the airy signs, and later in the book retells the myth in which Uranus, lord of space, is dethroned by Saturn, god of time.

Modern astrology made Uranus the ruler of Aquarius beside Saturn, and reads it for sudden change, invention and breaks with convention. Uranus takes about 84 years to circle the zodiac, so in transit astrology its opposition to its own natal place falls near the age of 42 and is read as a mid-life turning point.

Often confused with

Saturn: the ancient ruler of Aquarius and the outermost planet Ptolemy knew, where Uranus is the modern planet beyond it; Leo makes Saturn the planet that individualises and Uranus the fully individualised consciousness. Chiron: the small body orbiting between Saturn and Uranus, read as the wounded healer, where Uranus is a full planet read for freedom and change.

In Practice

Leo's own condition is a useful discipline. Before reading anything into Uranus in a chart, check it against his test: is it on an angle or in an airy sign, and does it aspect the Sun or the Moon, or at least Mercury and Venus? Where the answer is no, Leo himself doubted that its influence could be felt.
