Pluto Mythology

Lord of the Underworld: from Hades to Tombaugh

Pluto was found in 1930 in Arizona by comparing photographic plates taken on different nights. It took its name from the Roman god of the underworld, Pluto, at the suggestion of eleven-year-old Venetia Burney. The name Pluto means 'the wealthy one' and is the softened name of the Greek Hades. That god is lord of the mines and of the seed that waits beneath the soil, and he is also the invisible king who abducted Persephone. The planet was reclassified as a dwarf planet in 2006, and that decision changed nothing about the mythology it carries.

This page tells the myths the planet is named after. In classical astrology Pluto has no rulership. Scorpio traditionally belongs to Mars, and in this school it stays that way. The rulership of Scorpio that modern astrology assigns to Pluto is not used here.

Key facts

Symbolism map: underworld, wealth, abduction and return

The glyph sits at the centre of the map. The branches of Pluto's symbolism are arranged around it, with the gods in gold, the archetypes in blue, the traditions in green and the narratives in red. Tap a branch and its explanation opens below the map.

Hades / PlutoThe Greek tradition

Hades is the son of Cronus and Rhea. When the brothers divide the world by lot, the underworld falls to him. He owns a cap that makes its wearer invisible. The Greeks avoided speaking his name and called him Pluto, 'the wealthy', or Clymenus, 'the renowned', instead. He is the one who abducts Persephone. He is lord of the dead, but he is not death itself. Death is Thanatos. Hades in the Greek family tree →

Dis Pater and OrcusThe Roman tradition

Dis Pater means 'wealthy father' and is the Latin rendering of Pluto. Caesar writes that the Gauls traced their descent from Dis Pater. Orcus is the underworld god of oaths and punishment. The English word 'ogre' is commonly derived from Orcus by way of Italian orco, but the etymology is disputed. Some linguists trace the word instead to Hongrois, an old name for the Hungarians (Oghur). The planet's name, Pluto, was chosen from this Roman tradition.

Ereshkigal and NergalThe Mesopotamian tradition

Ereshkigal is queen of the underworld and the elder sister of Inanna. She rules her realm from behind seven gates. Nergal descends, overpowers her and becomes king at her side as her husband. So the underworld belongs first to the queen alone and is later ruled by the pair. Ereshkigal in the Mesopotamian family tree →

Osiris and AnubisThe Egyptian tradition

Osiris is king of the dead and embodies resurrection in his own body. Seth dismembers him and Isis gathers the pieces. Anubis embalms the dead and weighs the heart at judgement. In Egypt the underworld, the Duat, is a place of renewal rather than punishment. Ra passes through it every night and is born again at dawn. Osiris in the Egyptian family tree →

YamaThe Hindu tradition

Yama was the first human to die, and for that reason he became king of the dead. His two dogs meet the arriving souls. He rides a buffalo and carries a noose. He is regarded as the judge of dharma. In Buddhist Asia he passes into China and Japan as the judge of hell, where the Japanese call him Enma.

HelThe Norse tradition

Hel is the daughter of Loki. Half of her body is living and half is dead. She rules Helheim, where those who die of sickness and old age go. When Baldr dies the gods ask for him back, and Hel refuses. Those who die in battle do not come to her. They go to Odin and Freyja. Hel in the Norse family tree →

IzanamiThe Japanese tradition

Izanami is the mother goddess who died giving birth to the fire kami. Her husband Izanagi sets out to bring her back from Yomi, but he flees when he sees her rotting body. Izanami then becomes ruler of Yomi. She calls after Izanagi that she will kill a thousand people every day, and Izanagi answers that he will have fifteen hundred born every day.

Underworld and invisibilityThe cap made by the Cyclopes

The cap of Hades, called the kyneē, makes its wearer invisible. Perseus borrows it on his way to Medusa. The underworld is the place of what is not seen, not spoken and not named. For that reason everything repressed, buried or hidden is tied to this image.

WealthPlutus, the mine and the seed

The name Pluto means 'wealthy'. The mines lie underground, and the seed waits beneath the soil. Demeter's son Plutus, whose name means wealth, shares a root with Pluto. That is why the lord of the underworld is also regarded as the keeper of the treasure. Plutus in the family tree →

Abduction and returnPersephone's descent and the seasons

Persephone goes down to the underworld, spends part of the year there and comes back. This descent and return traces the cycle of the seed, of winter, of mourning and of spring. Inanna's descent to the underworld follows the same pattern. The mysteries of Eleusis let their initiates live through this descent and return. Persephone in the family tree →

Death and judgementThe weighing of the heart and the three judges

In Egypt the heart of the dead is weighed against a feather. In Greece the dead are judged by Minos, Rhadamanthys and Aeacus. In India the souls are received by Yama, and in Scandinavia by Hel. In these stories the underworld is not only an end but also a place of reckoning.

The abduction of PersephoneFrom the Homeric Hymn to Demeter

Kore bends down to pick a narcissus in the meadow of Nysa. At that moment the earth splits open, and Hades comes up in his golden chariot and carries her off. Demeter searches for nine days with torches in her hands and leaves the earth barren. Zeus finally sends Hermes down to the underworld. Hades lets the girl go, but before she leaves he feeds her a pomegranate seed. Because of that seed Persephone will spend a third of every year below.

Orpheus in the underworldAs told by Virgil and Ovid

Orpheus softens Charon first, then Cerberus and Hades, with his lyre. He is allowed to take Eurydice back on one condition: he must not look behind him until they reach the light. Before he reaches the exit he turns and looks, and Eurydice dies a second time. Virgil tells the story in the Georgics and Ovid in the Metamorphoses. Orpheus in the family tree →

The dot on the plateTombaugh's discovery of 1930

Percival Lowell searched for years for a body he called 'Planet X' and died without finding it. In 1930 twenty-four-year-old Clyde Tombaugh laid the plates he had photographed night after night side by side in a blink comparator. On 18 February he saw a dot in Gemini that had moved. In Oxford eleven-year-old Venetia Burney proposed the name, and Pluto was accepted. In 2006 the International Astronomical Union classed it as a dwarf planet.

P and LThe glyph ♇ from Lowell's initials

Pluto's glyph ♇ is a monogram of Percival Lowell's initials and carries no mythological meaning. Some astrologers use the sign ⯓ instead, which is built on the circle, crescent and cross scheme. Both glyphs were invented in the 20th century.

PlutoniumThe element named in 1941

Element 94, the one after neptunium, was named plutonium in 1941. This material was used in the first atomic bomb. The name of the underworld god was thus given to a destructive power. This is a naming tradition, not a classical metal correspondence.

In modern astrologyGiven for information, not used in this school

Twentieth-century astrology gave Pluto the meanings of transformation, power, obsession and death and rebirth, and assigned it the sign Scorpio. In the classical tradition Scorpio is the night house of Mars. This school does not use the modern rulership and treats Pluto as an indicator outside the dignities.

Meaning of the glyph: ♇

Pluto's common glyph ♇ is a monogram of Percival Lowell's initials P and L. The sign was designed as a tribute to the man who began the search for the planet, and it carries no mythological meaning. Some astrologers prefer the sign ⯓, in which the circle for spirit and the crescent for receptivity stand on the cross for matter. That one too was designed in the 20th century. Unlike the glyphs of the seven classical planets, neither of them comes from tradition.

P + LThese are Percival Lowell's initials, and they commemorate the history of the discovery.
⯓This is the alternative astrological glyph, with a crescent above a cross and a circle inside the crescent.
WholeThe sign is a modern invention and carries no mythological origin.

The lord of the underworld across cultures

In some cultures the underworld is a place of punishment. Tartarus and Orcus are of that kind. In others it is a place of renewal, as Egypt's Duat and Eleusis were understood. Its lord is sometimes a god such as Hades or Yama, and sometimes a goddess such as Ereshkigal, Hel or Izanami. In the cases of Hades and Persephone and of Ereshkigal and Nergal, a couple rules the realm.

Three myths

The pomegranate seed

Kore is gathering flowers in the meadow with the daughters of Oceanus when she sees the hundred-headed narcissus that Gaia grew for Hades, and she bends down to pick it. At that moment the earth splits open. Hades comes up with his immortal horses and takes the girl into his chariot. Only Hecate and Helios hear her cry. Demeter searches for her daughter for nine days without food or drink. When she learns the truth from Helios she leaves Olympus. The earth turns barren, people begin to die of hunger and the offerings to the gods cease. Zeus finally yields and sends Hermes down. Hades lets the girl go, but as she leaves he secretly puts a pomegranate seed in her mouth, because whoever eats in the underworld returns to it. From then on Persephone spends a third of the year with her husband. The Homeric Hymn to Demeter tells how Demeter then taught her mysteries to the people of Eleusis.

Nergal in the underworld

The gods hold a feast. Ereshkigal cannot leave the underworld, so she sends her vizier Namtar to the table in her place. When Namtar enters everyone stands, and only Nergal stays seated. Ereshkigal demands that Nergal be sent to her to answer for the insult. On Ea's advice Nergal takes fourteen demons with him, passes the seven gates, seizes Ereshkigal by the hair and drags her from her throne. The queen offers to make him her husband and king of the underworld. Nergal kisses her and takes the throne. In another version of the text Nergal makes love to her for six days and then flees. Ereshkigal sends word to Anu that she will let the dead loose upon the earth unless Nergal is sent back. The Amarna and Sultantepe texts preserve these two versions separately.

Venetia's suggestion

Percival Lowell believed that a 'Planet X' was disturbing the orbits of Uranus and Neptune, and he began the search at his observatory in Flagstaff. He died in 1916. Clyde Tombaugh, a Kansas farm boy taken on at the observatory in 1929, photographed plates every night and compared them days later. On 18 February 1930 he found a dot that had moved between two plates. When the news reached Oxford, eleven-year-old Venetia Burney suggested to her grandfather at breakfast that the name should be Pluto, because the name of the dark, distant and invisible god suited the new planet. The suggestion went by telegram to Flagstaff and was accepted unanimously. The initials P and L also commemorated Lowell.

Pluto in classical astrology: no rulership

RulershipNone. In classical astrology Scorpio is the night house of Mars and remains so. Giving Pluto the rulership of Scorpio is a modern practice that settled after the discovery of 1930, and it is not used in this school.
Exaltation, detriment, fallNone. Pluto has no place in the dignity tables.
SectNone.
JoyNone.
Day, hour, metalNone. The planetary days and hours are built on the seven classical planets. Plutonium is only a name, not a metal correspondence.
DiscoveryClyde Tombaugh found it on 18 February 1930 at Lowell Observatory. It has been classed as a dwarf planet since 2006.
OrbitOne orbit around the Sun takes about 248 years. Because the orbit is eccentric, Pluto stays between 12 and 31 years in a sign. It is retrograde for about 5 months of the year.
Place in classical interpretationIt may be observed as an additional indicator in the birth chart. It does not enter the calculation of dignity, almuten, planetary hours or sect. In mundane astrology it is used as a generational marker.

In this school the modern planets are seen in the chart, but they rule no sign. For the classical ruler of Scorpio see Mars Mythology.

Frequently Asked Questions

Does Pluto have a rulership in classical astrology?

No. In the classical tradition Scorpio is the night house of Mars. Giving Pluto the rulership of Scorpio is a modern practice that settled after the discovery of 1930. This school uses the dignities of the seven traditional planets. Pluto is observed in the chart, but it rules no sign.

Where does Pluto get its name?

It takes its name from the Roman god of the underworld, Pluto. That name is the euphemism for the Greek Hades and means 'wealthy'. Eleven-year-old Venetia Burney proposed it in Oxford in 1930. The fact that the initials commemorated Percival Lowell made it easier to accept. The moons also take their names from the underworld. Charon, Styx and Kerberos are among them.

Are Hades and Pluto the same?

Yes, they are the same god. Hades is his Greek name. Pluto, or Plouton, is his euphemistic name meaning 'wealthy', which the Romans translated as Dis Pater. The Greeks avoided speaking the name of Hades. Hades is not death itself but the king of the land of the dead. The god who stands for death is Thanatos.

Is Pluto still a planet?

In astronomy it has been a dwarf planet since 2006. Modern schools of astrology go on using it. Classical astrology works with the seven planets in any case. This page tells the planet's mythology and does not enter the debate over its status.

What does the Pluto glyph show?

♇ is made of the initials P and L of Percival Lowell. ⯓ is an astrological alternative designed in the 20th century. Neither has a mythological origin.
