History

Ptolemy's Tetrabiblos places Venus's exaltation in Pisces and her depression in Virgo, because she is moist by nature and increases her power in Pisces, where the moist spring begins.1

In Mesopotamian omen literature, Venus was linked to the goddess Ishtar, and the omens concerning Ishtar covered planetary events such as first and last visibilities, stations, and acronychal risings.2

Britannica's astrology article, written by David E. Pingree, says the Enūma Anu Enlil omens were grouped under four chief gods, with the Venus-related category named after Ishtar.2

Venus was visited for the first time in 1961 by Venera 1, which flew past the planet, achieving the first interplanetary spaceflight.3

What classical and modern sources say

Classical view

In Ptolemy's Tetrabiblos, Venus is described as having the same powers and tempered nature as Jupiter, though acting in the opposite way. Ptolemy writes that she warms moderately because of her nearness to the sun, but chiefly humidifies, like the moon. For this reason the ancients counted Venus, together with Jupiter and the moon, among the beneficent planets, because of their tempered nature and their abundance of the hot and the moist. Ptolemy also classes Venus with the moon as feminine, since both share more largely in the moist, and he places her exaltation in Pisces and her depression in Virgo.1

Modern view

Modern readers commonly describe Venus through the principles of harmony, femininity, beauty, refinement, affections, and love. The Wikipedia article on planets in astrology associates Venus with romantic relations, marriage and business partnerships, the arts, and fashion. Practitioners who work in this newer vocabulary often present Venus as an invitation to practise sympathy, cooperation, and the sincere uniting of oneself with others, and they treat difficulties in love or partnership as chances to grow in honesty and balance. This psychological language is an addition to the older rulership and sect structures rather than part of them.53

Rulership, cycles and traditional nature

Traditional rulership

Venus rules Taurus and Libra in the Wikipedia article Planets in astrology. Ptolemy's Tetrabiblos gives Venus its exaltation in Pisces and its depression in Virgo. These are symbolic table relationships, not claims of physical control over the signs or the people born under them.51

Sect and nature

Ptolemy's Tetrabiblos assigns Venus to the night sect and describes her as temperate and moist, warming moderately while chiefly humidifying like the moon. Sect is the classical method of grouping the planets into day and night divisions, and these classifications are historical symbolic labels rather than measured properties of the planet.1

Orbital cycle

Planets in astrology says Venus orbits the Sun in about 225 days, spending roughly 18.75 days in each zodiac sign. The Venus article reports that a Venusian solar year is 224.7 Earth days. These measured cycles are kept separate from the astrological interpretation built on top of them.53

Modern vocabulary

Modern astrological writing associates Venus with harmony, femininity, beauty, refinement, affections, and love, and the Planets in astrology article adds romantic relations, marriage and business partnerships, the arts, and fashion. Practitioners often present these themes as chances to practise sympathy, cooperation, and honest balance in relationships.5

The astronomy

Venus orbits closer to the Sun than Earth does. The orbits of Venus and Earth make the two planets approach each other in synodic periods of 1.6 years, and Venus comes closer to Earth than any other planet.3

A Venusian day is 116.75 Earth days long, about half a Venusian solar year, which is 224.7 Earth days long. Venus also has a very slow retrograde rotation about its axis.3

NASA lists an orbital period of 224.701 days.1

The diagram shows Venus's 224.7-day orbit against the 18.75 days it spends in each of the twelve zodiac signs, with Taurus and Libra marked as its rulerships.

Where astrologers differ

Ptolemy's Tetrabiblos classes Venus with the moon as feminine and nocturnal, because both share more largely in the moist and the night is more feminine. Britannica explains that Mercury's retrograde motion happens because Mercury orbits the Sun much faster than Earth, a different planet-specific phenomenon from the Venus omens described in the article. A Venusian day is 116.75 Earth days long, about half a Venusian solar year, which is 224.7 Earth days long. Venus also has a very slow retrograde rotation about its axis.

Worked out from the evidence

Reasoned from the cited facts, not stated outright by any one source.

Venus is a symbolic planet in Western astrology whose meaning rests on two traditions at once: the classical Ptolemaic table of rulerships and the later astrological vocabulary of love, harmony, and partnership.

Because the measured orbit of Venus is about 225 days while its astrological sign time is about 18.75 days, the astrological reading of Venus depends on a symbolic division of the zodiac rather than on the planet's physical motion.

Not yet confirmed

  • Whether the ancient sect and nature labels for Venus, such as night and moist, were ever tested against observed behaviour is not settled by the sources here.
  • How the Mesopotamian Ishtar omens about Venus relate to the later Greek and Roman rulership table is not described in the sources given.
