Pluto Mythology

Lord of the Underworld: from Hades to Tombaugh

Pluto was found in 1930 in Arizona by comparing photographic plates; on the suggestion of eleven-year-old Venetia Burney it took its name from the Roman god of the underworld, Pluto. Pluto, 'the wealthy one': the softened name of the Greek Hades, lord of the mines and the seed beneath the earth, the invisible king who abducted Persephone. In 2006 it was classed a dwarf planet; its mythology did not change.

This page tells the myths the planet is named after. In classical astrology Pluto has no rulership: Scorpio belongs traditionally to Mars and remains so. The rulership of Scorpio that modern astrology gives Pluto is not used in this school.

Key facts

Symbolism map: underworld, wealth, abduction and return

The glyph at the centre, the branches of Pluto's symbolism around it: gods (gold), archetypes (blue), traditions (green) and narratives (red). Tap a branch and its explanation opens on the right.

Hades / PlutoGreek

Son of Cronus and Rhea; he draws the underworld by lot. He has a cap that makes its wearer invisible, his name is not spoken: he is called 'Pluto' (the wealthy) and 'Clymenus' (the renowned). He abducts Persephone; lord of the dead but not death itself (that is Thanatos). Hades in the Greek family tree →

Dis Pater and OrcusRoman

Dis Pater, 'wealthy father', the Latin translation of Pluto; the Gauls derived themselves from him (Caesar). Orcus the underworld god of oaths and punishment; his name reaches as far as the English 'ogre'. The planet's name Pluto was chosen from this tradition.

Ereshkigal and NergalMesopotamian

Ereshkigal queen of the underworld, elder sister of Inanna; she rules behind seven gates. Nergal descends, overpowers her and becomes king as her husband. The underworld belongs first to the woman, then the pair rule. Ereshkigal in the Mesopotamian family tree →

Osiris and AnubisEgyptian

Osiris king of the dead and resurrection itself; Seth dismembers him, Isis gathers him. Anubis embalms and weighs the heart. In Egypt the underworld (Duat) is a place not of punishment but of renewal; Ra passes through it every night. Osiris in the Egyptian family tree →

YamaHindu

The first human to die and therefore king of the dead; his two dogs meet the souls, he rides a buffalo with his noose. Judge of dharma; in Buddhist Asia he passes to China and Japan as the judge of hell (Enma).

HelNorse

Daughter of Loki; half living, half dead. She rules Helheim, the land of those who die of sickness and old age, and does not give Baldr back. The battle-dead go not to her but to Odin and Freyja. Hel in the Norse family tree →

IzanamiJapanese

The mother who died bearing the fire kami; Izanagi goes to bring her back from Yomi and flees when he sees her rotting body. Izanami becomes ruler of Yomi: 'I will kill a thousand each day', Izanagi: 'I will have fifteen hundred born'. Izanami in the Japanese family tree →

Underworld and invisibilityThe cap of the Cyclopes

The cap of Hades (kyneē) makes its wearer invisible; Perseus borrows it on his way to Medusa. The underworld is what is not seen, not spoken, not named: the repressed, the buried, the hidden.

WealthPlutus, mine, seed

Pluto means 'wealthy': the mines are underground, the seed waits under the soil. Demeter's son Plutus (wealth) and Pluto share a root. The lord of the underworld is also the keeper of the treasure. Plutus in the family tree →

Abduction and returnPersephone, the seasons

Persephone descends to the underworld, stays part of the year, returns: the cycle of seed, winter, mourning and spring. Inanna's descent is the same pattern. The mysteries of Eleusis enacted this descent and return. Persephone in the family tree →

Death and judgementScales, three judges

In Egypt the heart is weighed against the feather; in Greece Minos, Rhadamanthys and Aeacus judge; in India Yama, in Norway Hel receives. The underworld is not only the end but the reckoning.

The abduction of PersephoneHomeric Hymn to Demeter

As Kore picks a narcissus in the meadow of Nysa the earth splits and Hades carries her off in his golden chariot. Demeter searches nine days with torches and leaves the earth barren; Zeus sends Hermes. As Hades lets the girl go he feeds her a pomegranate seed: a third of the year she will stay below.

Orpheus in the underworldVirgil, Ovid

Orpheus softens Charon, Cerberus and Hades with his lyre; he takes Eurydice back on one condition, that he not look behind him. Before reaching the light he turns and looks, and Eurydice dies a second time. What is taken from the underworld is lost when one looks back. Orpheus in the family tree →

The dot on the plateTombaugh, 1930

Percival Lowell searched for 'Planet X' and died without finding it. In 1930 twenty-four-year-old Clyde Tombaugh laid the plates he 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: Pluto. In 2006 the International Astronomical Union classed it a dwarf planet.

P and L♇, Lowell's initials

Pluto's glyph ♇ is a monogram of Percival Lowell's initials; not mythological. Some astrologers use an alternative glyph (⯓) in the circle-crescent-cross scheme; both are 20th-century inventions.

Plutonium1941

The element after neptunium (94) was named plutonium in 1941; the material of the first atomic bomb. The name of the underworld god was given to destructive power. A naming tradition, not a classical metal correspondence.

In modern astrologyFor information; not used in this school

20th-century astrology gave Pluto the meanings of transformation, power, obsession, death and rebirth, and the sign Scorpio. In the classical tradition Scorpio is the night house of Mars; this school does not use the modern rulership and keeps Pluto as an indicator outside dignity.

Meaning of the glyph:

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

P + LPercival Lowell's initials; the signature of the history of discovery.
Alternative astrological glyph: a crescent above a cross with a circle inside.
WholeA modern invention; carries no mythological origin.

The lord of the underworld across cultures

In some cultures the underworld is a place of punishment (Tartarus, Orcus), in others of renewal (Egypt's Duat, Eleusis). Its lord is sometimes a god (Hades, Yama), sometimes a goddess (Ereshkigal, Hel, Izanami), sometimes a couple (Hades and Persephone, Ereshkigal and Nergal).

Three myths

The pomegranate seed

Kore, gathering flowers in the meadow with the daughters of Oceanus, sees the hundred-headed narcissus Gaia grew for Hades and bends down; the earth splits, Hades comes up with his immortal horses and takes the girl into his chariot. Only Hecate and Helios hear her cry. Demeter searches nine days without food or drink, learns the truth from Helios and leaves Olympus; the earth turns barren, people die of hunger, offerings to the gods cease. Zeus yields and sends Hermes. Hades lets the girl go but as she leaves secretly puts a pomegranate seed in her mouth: whoever eats below returns below. Persephone will spend a third of the year with her husband; Demeter teaches her mysteries at Eleusis.

Nergal in the underworld

The gods hold a feast; Ereshkigal, unable to leave the underworld, sends her vizier Namtar. Everyone stands, Nergal does not. Ereshkigal demands him. On Ea's advice Nergal passes the seven gates with fourteen demons, seizes Ereshkigal by the hair and drags her from the throne. The queen says 'be my husband, be king'; Nergal kisses her and becomes king of the underworld. In another telling they make love for six days and he flees, and Ereshkigal sends word to Anu: 'send him back, or I will let the dead loose upon the earth'. The underworld does not release its lover.

Venetia's suggestion

Percival Lowell believed a 'Planet X' was disturbing the orbits of Uranus and Neptune and began the search at 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 said to her grandfather at breakfast 'let it be Pluto': the dark, distant, invisible god. 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 is not used in this school.
Exaltation, detriment, fallNone; it has no place in the dignity tables.
SectNone.
JoyNone.
Day, hour, metalNone; the planetary days and hours are built on the seven planets (plutonium is a naming).
Discovery18 February 1930, Clyde Tombaugh, Lowell Observatory; a dwarf planet since 2006
OrbitAbout 248 years; because of its eccentric orbit between 12 and 31 years in a sign; retrograde about 5 months a year
Place in classical interpretationMay be observed as an additional indicator in the birth chart; it does not enter the calculation of dignity, almuten, planetary hours or sect. A generational marker in mundane astrology.

This school's approach: the modern planets are seen in the chart but do not rule. 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 rules no sign.

Where does Pluto get its name?

From the Roman god of the underworld Pluto, that is the euphemistic name of the Greek Hades meaning 'wealthy'. Eleven-year-old Venetia Burney proposed it in Oxford in 1930; that the initials commemorated Percival Lowell eased its acceptance. The moons too are named from the underworld: Charon, Styx, Kerberos.

Are Hades and Pluto the same?

Yes; Hades is the god's Greek name, Pluto (Plouton) 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; death is Thanatos.

Is Pluto still a planet?

In astronomy 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 its mythology and does not enter the debate over status.

What does the Pluto glyph show?

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