Historically,astrological andastronomical symbols have overlapped. Frequently used symbols include signs of thezodiac,planets,asteroids, and other celestial bodies. These originate from medieval Byzantine codices. Their current form is a product of the EuropeanRenaissance. Other symbols forastrological aspects are used in various astrological traditions.

History and origin

[edit]

Symbols for theclassical 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 Greek horoscope papyri, the Sun was depicted by a circle bearing the ancient glyph for radiance (old sun symbol), while the Moon was symbolized by a crescent.[2]

Classical planets

[edit]

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 stylizedcaduceus.[3]Annie S. D. Maunder finds antecedents of the planetary symbols in earlier sources, used to represent the gods associated with the classical planets.Bianchini'splanisphere, produced in the 2nd century,[4] shows Greek personifications of planetary gods charged with early versions of the planetary symbols: Mercury has acaduceus; Venus has, attached to her necklace, a cord connected to another necklace; Mars, a spear; Jupiter, a staff; Saturn, a scythe; the Sun, acirclet with rays radiating from it; and the Moon, a headdress with a crescent attached.[5] A diagram in Johannes Kamateros' 12th-centuryCompendium of Astrology shows the Sun represented by the circle with a ray, Jupiter by the letterzeta (the initial ofZeus, Jupiter's counterpart inGreek 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 (U+2609 SUN), 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.)[citation needed]The modern sun symbol resembles the Egyptianhieroglyph for "sun" – a circle that sometimes had a dot in the center, (U+131F3 𓇳EGYPTIAN HIEROGLYPH N005).Similar in appearance were several variants of the ancestral form of the modern Chineselogograph for "sun", which in theoracle bone script andbronze 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

[edit]

Symbols for Uranus, Neptune and Pluto were created shortly after their discovery. For Uranus, two variant symbols are seen. One symbol,Uranus, invented byJ. G. Köhler and refined byBode, was intended to represent the newly discovered metalplatinum; since platinum, sometimes described as white gold[a] was found by chemists mixed with iron, the symbol for platinum combines the alchemical symbols foriron, ♂, andgold, ☉.[6][7] An inverted version of that same symbol, was in use in the early 20th century.[8] Another symbol,Uranus, was suggested byJérôme Lalande in 1784. In a letter toWilliam Herschel, Lalande described it as "a globe surmounted by the first letter of your name" (French:un globe surmonté par la première lettre de votre nom).[9] After Neptune was discovered, theBureau des Longitudes proposed the name Neptune and the familiar trident for the planet's symbol, though at bottom may be either a crossNeptune or an orbNeptune.[10]Pluto, like Uranus, has multiple symbols in use. One symbol, ♇, is amonogram of the lettersPL (which can be interpreted to stand for Pluto or for astronomerPercival Lowell), was announced with the name of the new planet by the discoverers on May 1, 1930.[11] Another symbol, popularized in Paul Clancy'sAmerican Astrology magazine, is based on Pluto'sbident:⯓.[12]

Asteroids

[edit]

The astrological symbols for the first four objects discovered at the beginning of the 19th century —Ceres,Pallas,Juno andVesta — 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 afterGiuseppe Piazzi's discovery ofCeres, a group of astronomers ratified the name, proposed by the discoverer, and chose the sickle as a symbol of the planet.[13] The symbol for Pallas, the spear ofPallas Athena, was invented by Baron Franz Xaver von Zach, and introduced in hisMonatliche Correspondenz zur Beförderung der Erd- und Himmels-Kunde.[14]Karl Ludwig Harding, who discovered and named Juno, assigned to it the symbol of a scepter topped with a star.[15]

The modern astrological form of the symbol for Vesta, ⚶, was created by Eleanor Bach,[16] who is credited with pioneering the use of thebig four asteroids with the publication of herEphemerides of the Asteroids in the early 1970s.[17] The original form of the symbol for Vesta,Vesta, was created by German mathematicianCarl 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 goddessVesta, and also specified that the symbol should be the altar of the goddess with thesacred fire burning on it.[18][19]Bach's variant is a simplification of 19th-century elaborations of Gauss's altar symbol.[16]

Centaurs

[edit]

The symbol for the centaurChiron, ⚷, is both a key and a monogram of the letters O and K (for 'Object Kowal', a provisional name of the object, for discovererCharles 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."[20]

A widely used convention for othercentaurs, 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 orφ for Pholus and N for Nessus (U+2BDB PHOLUS,U+2BDC NESSUS).

Other trans-Neptunian objects

[edit]

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 softwareAstrolog, as well as being used less consistently by commercial programs.

Miscellaneous orbital stations

[edit]

The symbol forretrograde motion is ℞, a capital 'R' with a tail stroke.[23][24][25] An 'R' with a tail stroke was used toabbreviate many words beginning with the letter 'R'; in medical prescriptions, it abbreviated the wordrecipe[26] (from the Latin imperative ofrecipere "to take"[27]), and inmissals, an R with a tail stroke marked the responses.[26]

Asteroids and other celestial bodies

[edit]
Further information:List of asteroids in astrology

Since the 1970s, some astrologers have used asteroids and other celestial bodies in their horoscopes. The symbol for the first-recognisedcentaur,2060 Chiron, was devised by Al H. Morrison soon after it had been discovered byCharles Kowal, and has become standard amongst astrologers.[36] In the late 1990s, German astrologer Robert von Heeren created symbols for other centaurs based on the Chiron model, though only those for5145 Pholus and7066 Nessus are included in Unicode, and only that for Pholus in Astrolog.[37] 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.[38]

Lunar nodeAscendingNodeU+260ANot all astrologers use the lunar nodes; however, their usage is very important inVedic astrology. They are alternately known as the "Dragon's Head" (Rahu,Caput Draconis, orAnabibazon) and the "Dragon's Tail" (Ketu,Cauda Draconis, orCatabibazon). The two nodes together are most commonly referred to simply as thenodal axis, thelunar nodes, or theMoon's nodes.
DescendingNodeU+260B
LunarapogeeBlack Moon, or LilithU+26B8The original Black Moon was a fictitious second, very dark moon of Earth. It is now often re-interpreted as the position of the mean lunarapogee as measured from thegeocenter; 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'sbarycentric or topocentric position instead of its geocentric position.[46]
True Black MoonU+2BDEThe lunar apogee calculated from its current position (disregarding solar perturbation), as opposed to itsmean position.[37]
symbols related to LilithWhite Moon, or SelenaU+2BDDRussian astrologer Pavel Globa invented this to serve as the symbolic opposite of the Black Moon in the 1980s.[37]
True White Moon, or ArtaU+2BDFSimilar to White Moon, but calculated from the "true" Black Moon rather than the mean Black Moon.[37]
Solar apogee----Assumes an Earth-centered universe; the heliocentric equivalent would beterrestrial aphelion. Used to derive the (true) White Moon from the (true) Black Moon: ⯟ = ☊ + 7⁄4(⯞ −Solar apogee + 180°)

Anecdotum Parisinum. Mercury has two bars in the former but only one in the latter. Venus has a bar in the former but none in the latter. Jupiter has a vertical bar in both, and Saturn has a new horizontal bar in both. Mars doesn't have a bar because it would turn his spear into an arrow.[5]
