Astrological symbols explained

Astrological symbols should not be confused with Astronomical symbols.

Historically, astrological and astronomical symbols have overlapped. Frequently used symbols include signs of the zodiac and classical planets. These originate from medieval Byzantine codices. Their current form is a product of the European Renaissance. Other symbols for astrological aspects are used in various astrological traditions.

History and origin

Symbols for the classical planets, zodiac signs, aspects, lots, and the lunar nodes appear in the medieval Byzantine codices in which many ancient horoscopes were preserved.[1] In the original papyri of these Greek horoscopes, there was a circle with the glyph representing shine for the Sun; and a crescent for the Moon.[2]

Classical planets

The written symbols for Mercury, Venus, Jupiter, and Saturn have been traced to forms found in late Classical Greek papyri.[3] The symbols for Jupiter and Saturn are monograms of the initial letters of the corresponding Greek names, and the symbol for Mercury is a stylized caduceus.[3] A.S.D. Maunder finds antecedents of the planetary symbols in earlier sources, used to represent the gods associated with the classical planets. Bianchini's planisphere, produced in the 2nd century,[4] shows Greek personifications of planetary gods charged with early versions of the planetary symbols: Mercury has a caduceus; Venus has, attached to her necklace, a cord connected to another necklace; Mars, a spear; Jupiter, a staff; Saturn, a scythe; the Sun, a circlet with rays radiating from it; and the Moon, a headdress with a crescent attached.[5] A diagram in Johannes Kamateros' 12th-century Compendium of Astrology shows the Sun represented by the circle with a ray, Jupiter by the letter zeta (the initial of Zeus, Jupiter's counterpart in Greek mythology), Mars by a shield crossed by a spear, and the remaining classical planets by symbols resembling the modern ones, without the cross-mark seen in modern versions of the symbols.[5]

The modern sun symbol, pictured as a circle with a dot, first appeared in the Renaissance.[2] (The conventional symbols for the signs of the zodiac also develop in the Renaissance period as simplifications of the classical pictorial representations of the signs.)The modern sun symbol resembles the Egyptian hieroglyph for "sun"  - a circle that sometimes had a dot in the center, .Similar in appearance were several variants of the ancestral form of the modern Chinese logograph for "sun", which in the oracle bone script and bronze script were .It is not known if the Egyptian and Chinese logographs have any connection to the European astrological symbol.

Major planets discovered in the modern era

Symbols for Uranus and Neptune were created shortly after their discovery. For Uranus, two variant symbols are seen. One symbol,, invented by J. G. Köhler and refined by Bode, was intended to represent the newly discovered metal platinum; since platinum, sometimes described as white gold was found by chemists mixed with iron, the symbol for platinum combines the alchemical symbols for iron, ♂, and gold, ☉.[6] [7] An inverted version of that same symbol, was in use in the early 20th century.[8] Another symbol,, was suggested by Lalande in 1784. In a letter to Herschel, Lalande described it as "un globe surmonté par la première lettre de votre nom" ("a globe surmounted by the first letter of your name").[9] After Neptune was discovered, the Bureau des Longitudes proposed the name Neptune and the familiar trident for the planet's symbol, though at bottom may be either a cross or an orb .[10]

Asteroids

The astrological symbols for the first four objects discovered at the beginning of the 19th century — Ceres, Pallas, Juno and Vesta — were created shortly after their discoveries. They were initially listed as planets, and half a century later came to be called asteroids, though such "minor planets" continued to be considered planets for perhaps another century. Shortly after Giuseppe Piazzi's discovery of Ceres, a group of astronomers ratified the name, proposed by the discoverer, and chose the sickle as a symbol of the planet.[11] The symbol for Pallas, the spear of Pallas Athena, was invented by Baron Franz Xaver von Zach, and introduced in his Monatliche Correspondenz zur Beförderung der Erd- und Himmels-Kunde.[12] Karl Ludwig Harding, who discovered and named Juno, assigned to it the symbol of a scepter topped with a star.[13]

The modern astrological form of the symbol for Vesta, ⚶, was created by Eleanor Bach,[14] who is credited with pioneering the use of the big four asteroids with the publication of her Ephemerides of the Asteroids in the early 1970s.[15] The original form of the symbol for Vesta,, was created by German mathematician Carl Friedrich Gauss. Olbers, having previously discovered and named one new planet (as the asteroids were then classified), gave Gauss the honor of naming his newest discovery. Gauss decided to name the planet for the goddess Vesta, and also specified that the symbol should be the altar of the goddess with the sacred fire burning on it.[16] [17] Bach's variant was a simplification of 19th-century elaborations of Gauss's altar symbol.[14]

Centaurs

The symbol for the centaur Chiron, ⚷, is both a key and a monogram of the letters O and K (for 'Object Kowal', a provisional name of the object, for discoverer Charles T. Kowal) was proposed by astrologer Al Morrison, who presented the symbol as "an inspiration shared amongst Al H. Morrison, Joelle K.D. Mahoney, and Marlene Bassoff."[18]

A widely used convention for other centaurs, proposed by Robert von Heeren in the 1990s, is to replace the K of the Chiron key glyph with the initial letter of the object: e.g. P or φ for Pholus and N for Nessus .

Trans-Neptunian objects

Pluto, like Uranus, has multiple symbols in use. One symbol, ♇, is a monogram of the letters PL (which can be interpreted to stand for Pluto or for astronomer Percival Lowell), was announced with the name of the new planet by the discoverers on May 1, 1930.[19] Another symbol, which was popularized in Paul Clancy's astrological publications, is based on Pluto's bident: . This symbol is described by Dane Rudhyar as "suggest[ing] the planetary character of the Pluto mind by the circle, floating above the open cup." Although, this meaning is readily debatable due to Blavatskian origins, rather than a properly traditional understanding, such as may be found in Hermeticism.[20]

Symbols for other large trans-Neptunian objects have mostly been proposed on the Internet;[21] some created by Denis Moskowitz have been used by NASA[22] and are used by the popular open-source astrological software Astrolog, as well as being used less consistently by commercial programs.

Miscellaneous orbital stations

The symbol for retrograde motion is, a capital 'R' with a tail stroke.[23] [24] [25] An 'R' with a tail stroke was used to abbreviate many words beginning with the letter 'R'; in medical prescriptions, it abbreviated the word recipe (from the Latin imperative of recipere "to take"[26]), and in missals, an R with a tail stroke marked the responses.[27]

Asteroids and other celestial bodies

Since the 1970s, some astrologers have used asteroids and other celestial bodies in their horoscopes. The symbol for the first-recognised centaur, 2060 Chiron, was devised by Al H. Morrison soon after it had been discovered by Charles Kowal, and has become standard amongst astrologers.[33] In the late 1990s, German astrologer Robert von Heeren created symbols for other centaurs based on the Chiron model, though only those for 5145 Pholus and 7066 Nessus are included in Unicode, and only that for Pholus in Astrolog. The following list is by no means exhaustive, but for bodies outside this list, there is often very little to no independent usage beyond the symbols' creators.

Miscellaneous symbols

CategoryNameImageTextUnicodeExplanation
The ascendant (also known as the "ascensum coeli") is the rising intersection of the ecliptic with the celestial horizon at a particular moment in time; it is used in the construction of a horoscope/natal chart
MidheavenThe midheaven (also known as the "medium coeli") is the point where the ecliptic crosses the local meridian; it is used in the construction of a horoscope/natal chart
or or U+1F70A The vertex and anti-vertex are the points where the prime vertical intersects the ecliptic. A crucible symbol,, is used by Astrolog and the HamburgSymbols font
Apparent retrograde motion Retrograde motionU+211E Symbol represents the apparent retrograde motion of a planet in an astrological chart
Ascending NodeU+260ANot all astrologers use the lunar nodes; however, their usage is very important in Vedic astrology. They are alternately known as the "Dragon's Head" (Rahu, Caput Draconis, or Anabibazon) and the "Dragon's Tail" (Ketu, Cauda Draconis, or Catabibazon). The two nodes together are most commonly referred to simply as the nodal axis, the lunar nodes, or the Moon's nodes.
Descending NodeU+260B
Black Moon, or Lilith U+26B8 The original Black Moon was a fictitious second, very dark moon of Earth. It is now often re-interpreted as the position of the mean lunar apogee as measured from the geocenter; variants of the Black Moon include replacing the mean orbit with a "true" osculating orbit or with an interpolated orbit; charting the empty focus of the Moon's orbit instead of the apogee; and measuring the desired point's barycentric or topocentric position instead of its geocentric position.[42]
True Black Moon U+2BDE The lunar apogee calculated from its current position (disregarding solar perturbation), as opposed to its mean position.
symbols related to Lilith White Moon, or Selena U+2BDD Russian astrologer Pavel Globa invented this to serve as the symbolic opposite of the Black Moon in the 1980s.
True White Moon, or Arta U+2BDF Similar to White Moon, but calculated from the "true" Black Moon rather than the mean Black Moon.
Solar apogee -- -- Assumes an Earth-centered universe; the heliocentric equivalent would be terrestrial aphelion. Used to derive the (true) White Moon from the (true) Black Moon: ⯟ = ☊ + 7⁄4(⯞ - + 180°)
Alchemical 'Three primes'U+1F70DWestern astrological symbolism has common early origin with alchemical shorthand glyphs, and planetary divination has long been held in association with alchemy's symbols; the three primes of Paracelsus have been associated with the zodiac sign modalities, and tendencies of their nature in an elementary way to be construed as being mutable (Quick-Silver or Mercury), fixed (Salt) or be cardinal (Sulfur).
U+1F714
U+263F
Serpent-holder U+26CE Ophiuchus has been proposed as a thirteenth sign of the zodiac by astrologer Walter Berg in 1995, who gave it a symbol which gained some popularity in Japan.
EarthU+1F728 Four quadrants of the Earth
Lot of fortuneU+1F774 Glyph for planet Earth rotated 45 degrees. In some fonts the tensor product, U+2297 ⊗, can be used as a substitute for the symbol.
