What sets Jupiter apart
Jupiter takes close to twelve years to circle the zodiac, so it spends about a year in each sign and its sign changes mark a rhythm no other planet has. Ptolemy calls it temperate, warm and moist with warmth ahead, and so the greater benefic, set between cold Saturn and fiery Mars. It leads the diurnal sect with the Sun. Meeting Saturn about every 20 years, it makes the Great Conjunctions that Abu Ma'shar made the base of his reading of history.
- Circuit of the zodiac: about 11.86 years
- Time in a sign: about a year, from roughly 12 to 13 months
- Retrograde: about four months in each year
- Great Conjunction: meets Saturn about every 19.9 years, the Jupiter and Saturn cycle
- Exaltation degree: 15 degrees of Cancer in the later tradition
- Joy: the eleventh house, the Good Spirit
A one-minute story
The Wandering Stars
How the moving planets were watched, named and found, and what a transit is.
Jupiter in the traditional textbooks
Jupiter is the first benefic in Burgoyne's ranking. Ptolemy calls him temperate, warm and moist, set between cold Saturn and fiery Mars, with fertilizing breezes. Firmicus names the eleventh house the Good Spirit and says it is Jupiter's place. Dorotheus says Jupiter or Venus in an angle frees a slave, with Jupiter in Capricorn excepted, and that Jupiter well placed gives gain from nobles and kings.
- Nature (Ptolemy): Jupiter is temperate, warm and moist, with warmth leading, between Saturn and Mars, with fertilizing breezes.
- Class (Ptolemy): benefic.
- Sex (Ptolemy): masculine. Team: the day team.
- Sphere (Firmicus): the second sphere, below Saturn.
- Egyptian name (Firmicus): Phaethon.
- Color (Ptolemy, reading eclipses and comets): white.
- Orb (Abu Ma'shar): 9 degrees.
- Body (Ptolemy): the hand, lungs, arteries and seed. Body (Burgoyne, 1896): the arterial system.
Jupiter: dignities, bounds and strength
Where Jupiter is strong, according to the same few authors:
- Domicile: Sagittarius and Pisces. Ptolemy's reason: they are in trine to the houses of the luminaries, airy and fruitful.
- Detriment: Gemini and Virgo, the signs opposite its own.
- Exaltation: 15 degrees of Cancer, because Cancer is the most northerly point, with the strongest northern breezes (Ptolemy). Fall: 15 degrees of Capricorn.
- Joy by sign (Dorotheus): Sagittarius. Joy by house (al-Qabisi): the eleventh house.
- Triplicity: night lord of the fire signs (Aries, Leo and Sagittarius); partner of the air signs (Gemini, Libra and Aquarius) (Dorotheus).
The Egyptian bounds of Jupiter add up to 79 degrees of the 360. Aries 1 to 6, Taurus 15 to 22, Gemini 7 to 12, Cancer 20 to 26, Leo 1 to 6, Virgo 18 to 21, Libra 15 to 21, Scorpio 20 to 24, Sagittarius 1 to 12, Capricorn 8 to 14, Aquarius 14 to 20, Pisces 13 to 16. The widest is 12 degrees, in Sagittarius, and the narrowest is 4, in Virgo and Pisces.
Jupiter rules 5 of the 36 decans: first decan of Gemini, second decan of Leo, third decan of Libra, first decan of Capricorn, second decan of Pisces.
- Facing (al-Qabisi, after Ptolemy): a western planet is in the facing of the Sun when it stands in the fifth sign from the Sun, as many signs as its domicile is from the Sun's.
- Face (Ptolemy, a phase and not a decan): it makes trine to the Sun.
- Morning star (Firmicus): it becomes one when it precedes the Sun by 12 degrees.
Jupiter: people, years and the limb in each sign
Burgoyne calls Jupiter the planet of authority, law, order, commerce and theology, electric and health-giving, and gives him the arterial system. Firmicus gives his Egyptian name as Phaethon. In Hill's candlestick he stands with Mars and Saturn on the outer side.
Among siblings, Dorotheus assigns it middle brothers (with Mars); when it rules the second house, he traces a decline in fortune to a nobleman, a king or a government. Dorotheus's figure for the years of evil an angular planet holds off is 12 years. Ptolemy says that as lord of an eclipse he brings prosperity, peace, favors from kings and healthy air.
Al-Qabisi gives each planet a limb in each sign, the part that shows illness when it is troubled there. For Jupiter:
- Aries: belly
- Taurus: chest
- Gemini: private parts
- Cancer: thighs
- Leo: thighs and knees
- Virgo: knees
- Libra: eyes
- Scorpio: feet
- Sagittarius: legs and head
- Capricorn: knees and eyes
- Aquarius: shoulders, chest, feet
- Pisces: heart and head
