Eris Mythology

From the daughter of Nyx to the debate over a tenth planet

Eris is the dwarf planet found in photographs that Mike Brown, Chad Trujillo and David Rabinowitz took at Palomar Observatory on 21 October 2003. The team noticed the object on 5 January 2005 and announced it in July 2005. Because Eris is more massive than Pluto, it forced the International Astronomical Union to define a planet for the first time in 2006.

It is named after Eris, the goddess of strife and contention. In classical astrology Eris has no rulership, exaltation, sect or joy. This page describes the place of the goddess in the ancient sources, how the story of the golden apple appears in each source, and how the body came to be named.

Key facts

Symbolism map: strife, rivalry and the apple

The glyph of Eris stands at the centre. The branches around it show the symbolism in four colours: gods in gold, archetypes in blue, traditions in green and narratives in red. Touch a branch and its explanation opens below the map.

Daughter of NyxTheogony 225

When Hesiod lists the children that Night (Nyx) bore without a father, he names Eris among them. He then lists the children of Eris herself: Ponos (toil), Lethe (forgetting), Limos (famine), Algea (pains), battles, quarrels, lies, Dysnomia (lawlessness), Ate (ruin) and Horkos (oath). This lineage presents Eris as the mother of the troubles in human life. Eris in the Greek family tree →

Two ErisesWorks and Days 11-26

At the opening of Works and Days, Hesiod says that there is not one Eris on earth but two. One fosters war and contention, and nobody loves her. The other is the elder daughter of Night, and Zeus set her in the roots of the earth. This second Eris drives even the idle man to work, because a man who sees his neighbour growing rich sets to work himself.

The archetype of competitionPotter against potter

Hesiod describes the good Eris through examples. The potter envies the potter, the carpenter the carpenter, the beggar the beggar and the singer the singer. This kind of envy does not destroy but produces. The passage on this side of Eris is the oldest Greek text to say that strife is not always bad.

Sister of AresIliad IV

In the fourth book of the Iliad, Homer introduces Eris as the sister and companion of Ares. She starts small, and then her head strikes the sky while her feet still walk on the earth. Homer uses this image to show how a quarrel grows from a small word until it draws everyone in. Ares on the Mars page →

The cry over the shipsIliad XI

In the eleventh book of the Iliad, Zeus sends Eris to the Achaean ships with the portent of war in her hands. Eris climbs onto the ship of Odysseus, which stands in the middle of the line, and gives a great cry. The cry makes war seem sweeter to the Achaeans than going home.

The shield of AchillesIliad XVIII

In the battle scene on the shield that Hephaestus made for Achilles, Eris moves among the fighters together with Kydoimos (tumult) and Ker (death). Here Homer shows Eris as a personified force, as one of the figures inside the battle.

The wedding of Peleus and ThetisSummary of the Cypria

According to the summary of the lost epic Cypria preserved by Proclus, Eris starts a quarrel over beauty among Hera, Athena and Aphrodite at the wedding of Peleus and Thetis. Zeus then tells Hermes to take the goddesses to Alexandros (Paris) on Mount Ida. This summary does not mention an apple.

The golden appleLater sources

In the Epitome of Apollodorus (3.2) the apple appears as an object that Eris throws to the goddesses as a prize for beauty. Hyginus (Fabulae 92) writes that Eris was not invited to the wedding, threw the apple through the door and said that the fairest should take it. Lucian also mentions the inscription on the apple, and Colluthus links the apple to the garden of the Hesperides. The best known details of the story are therefore found not in the oldest source but in later ones. Aphrodite on the Venus page →

The judgement of ParisThe road to Troy

The goddesses appear before Paris on Mount Ida. Hera promises him sovereignty, Athena promises victory in war, and Aphrodite promises Helen. Paris chooses Aphrodite and carries Helen off from Sparta. Homer recalls this judgement only once, in the last book of the Iliad, and does not name Eris.

AteTwo different lineages

Ate is blindness and ruin. Hesiod makes her a daughter of Eris. Homer, in the nineteenth book of the Iliad, calls Ate the eldest daughter of Zeus and tells how Zeus seized her by the hair and threw her from the sky. The two sources give the same figure different parents, and both versions were in use in antiquity. Ate in the family tree →

DysnomiaLawlessness

Dysnomia is one of the daughters of Eris in Hesiod's list, and her name means bad order or lawlessness. Her opposite is Eunomia, good order. The moon of the dwarf planet, found in 2005, was given this name.

HorkosOath

Hesiod ends the list of the children of Eris with Horkos and says that he is the power that does most harm to those who knowingly swear false oaths. Works and Days says that the Erinyes assisted at the birth of Horkos on the fifth day of the month. Some linguists connect the name of Orcus, the Roman god of the underworld, with Horkos, but the connection is disputed. Orcus page →

DiscordiaRome

In Rome the counterpart of Eris is Discordia. In the sixth book of the Aeneid, Virgil places her at the entrance to the underworld with her snake hair bound in bloody ribbons. In the eighth book she moves through the middle of the battle of Actium on the shield of Aeneas, wearing a torn cloak.

The strife of HeraclitusFragment 80

Heraclitus of Ephesus writes that war is common to all, that justice is strife (eris), and that all things come into being through strife and necessity. This sentence turns Eris from a goddess into a principle that explains how the cosmos works.

The Hand of ErisPrincipia Discordia

The half-humorous Principia Discordia, written in the 1960s by Greg Hill and Kerry Thornley, started the movement called Discordianism, which makes Eris its chief goddess. The five-fingered 'Hand of Eris' is a symbol drawn in that text. When the dwarf planet was named, this symbol came into use as its sign.

The tenth planet debate2005-2006

Until an official name was given, the discovery team informally called the object 'Xena'. Once it emerged that Eris might be larger than Pluto, people debated whether it should count as the tenth planet. On 24 August 2006 the International Astronomical Union defined a planet, and Pluto and Eris became dwarf planets. The name alludes to that debate.

Eris in modern astrologyAfter 2007

In 2007 the astrologer Henry Seltzer proposed a second glyph for Eris, and in 2015 he interpreted Eris in his book 'The Tenth Planet'. This interpretation is a personal modern reading, and no tradition shared and accepted among astrologers has formed. It has no connection with the classical system of dignities.

Meaning of the glyph:

Unicode has two signs for Eris, and both were added in 2018 with Unicode 11.0. The first (U+2BF0) is the 'Hand of Eris', which comes from the symbol in the Principia Discordia, and Denis Moskowitz adapted it as an astronomical sign. The second (U+2BF1) is a circle with a downward arrow, proposed by the astrologer Henry Seltzer in 2007. Because the fonts on this site do not contain these characters, the glyph here was drawn after the first form in the Unicode proposal (David Faulks, L2/16-173).

| Vertical strokeThis is the middle finger of the hand, and it forms the axis of the symbol.
)( Two arcsThe curves on the right and on the left are the other four fingers, and they meet in the middle.
- Short strokeThe horizontal line is the palm. The second form (U+2BF1) uses a circle and a downward arrow instead.

Strife and disorder across cultures

Figures that personify strife or disorder exist in many traditions. The counterparts below rest only on similarity of function. It cannot be said that these figures derive from Eris or are related to her.

Greek

Eris

In Hesiod she is the daughter of Nyx and a power with two separate faces. In Homer she joins the fighting beside Ares.

See in family tree
Roman

Discordia

Virgil shows her at the gate of the underworld and at the battle of Actium. In Rome she is not a goddess with a cult of her own but a force personified in poetry.

Norse

Loki

In the Lokasenna he comes to Ægir's feast and insults the gods one by one. The two share the motif of starting a quarrel at a feast of invited guests, but Loki is not a god of strife.

See in family tree
Egyptian

Seth

In the papyrus known as The Contendings of Horus and Seth he enters a long dispute over the throne. Seth is the god of disorder, but he also protects the boat of Ra.

Mesopotamian

Erra

In the Epic of Erra he sets the lands against one another and brings destruction. He is not personified strife like Eris but a god of war and plague.

Indian

Kali (demon of the age)

In the tale of Nala in the Mahabharata he enters Nala as strife in personified form and makes him lose at dice. He is not the same figure as the goddess Kālī, and their names are spelled differently.

Japanese

Susanoo

In the Kojiki he wrecks the rice fields of Amaterasu and causes chaos in heaven. In the end he is driven out of heaven. The similarity lies in the function of breaking order.

Three myths

Two Erises

Hesiod opens Works and Days by addressing his brother Perses and telling him that there are two kinds of Eris on earth. The first fosters evil war and contention, and people honour her unwillingly because the gods will it. The second is the elder daughter of Night, and Zeus placed her in the roots of the earth. This Eris sends even the man who will not work to his labour, because a man who sees his neighbour sowing and reaping turns back to his own field. Hesiod asks Perses to leave the bad Eris behind and to work his land instead of quarrelling over property in the courts. In the Theogony the same poet speaks of only one dark Eris, and the difference between the two texts caught the attention of ancient readers as well.

The goddess who was not invited to the wedding

The wedding of Peleus and Thetis is told as the starting point of the Trojan War. In the summary of the Cypria, Eris comes to the wedding and starts a quarrel over beauty among Hera, Athena and Aphrodite. Apollodorus writes that Eris threw an apple to the goddesses as a prize for beauty. Hyginus expands the story. In his version Eris has not been invited. She throws an apple through the door and says that the fairest will take it. Zeus does not want to give the verdict himself and sends the goddesses to Paris on Mount Ida. Paris chooses Aphrodite, and his choice leads to the abduction of Helen and to the war. The form of the story known today does not come from a single source but grew over the centuries as details were added.

The quarrel that starts small

In the fourth book of the Iliad the truce between the Trojans and the Achaeans breaks down and the two armies clash again. As Homer lists the powers that join the battle, he names Eris as the sister of Ares. At first Eris is small, then her head reaches the sky while her feet stay on the ground, and she moves through the crowd and multiplies the pain. In the eleventh book Zeus sends her again, and this time Eris shouts from above the ships. In Homer, Eris is less a person than a force that cannot be separated from war itself.

How it got its name

The team of Mike Brown, Chad Trujillo and David Rabinowitz noticed this object on 5 January 2005 in images taken on 21 October 2003 with the Samuel Oschin telescope at Palomar Observatory. The object received the provisional designation 2003 UB313 and was announced on 29 July 2005.

Until an official name arrived, the team called the object 'Xena' among themselves. When it became clear that Eris might be larger than Pluto, people debated whether it was the tenth planet. On 24 August 2006 the International Astronomical Union adopted a definition of a planet, and Pluto and this object entered the class of dwarf planets.

The name was approved on 13 September 2006. The naming citation of the Minor Planet Center describes Eris as the goddess who causes jealousy and strife among people, and it mentions the quarrel she started among the goddesses at the wedding of Peleus and Thetis. Brown chose the name because he found it fitting for the dispute that the discovery had caused among astronomers. Its moon was named after Dysnomia, the daughter of Eris.

Eris in classical astrology: no rulership

RulershipNone. In classical astrology domicile belongs to the seven traditional planets alone.
ExaltationNone. Degrees of exaltation are defined for the seven planets.
SectNone. The division by sect belongs to the classical seven.
JoyNone. Joy is tied to the house system and does not cover dwarf planets.
Type of bodyEris is a scattered disc object and a dwarf planet. Its diameter is about 2,326 kilometres.
DiscoveryThe images were taken on 21 October 2003, and Brown, Trujillo and Rabinowitz noticed the object at Palomar on 5 January 2005.
OrbitIt completes its circuit of the Sun in about 558 years. Its orbit is inclined 44 degrees to the ecliptic.
Modern useIt can be added to the chart in Thema. Its interpretation belongs to the modern literature written after 2005.

The position of this school is plain: Eris is not a planet and rules no sign. It has no place in the dignity table. Naturally, none of the classical sources mentions this body. For the detail see Essential and Accidental Dignities.

Frequently Asked Questions

Why did Eris end Pluto's status as a planet?

The mass of Eris is about 27 percent greater than that of Pluto. Counting it as the tenth planet would have meant counting the other large bodies still to be found in the Kuiper belt as planets too. In 2006 the International Astronomical Union defined a planet, and both became dwarf planets.

Is the story of the golden apple in Homer?

No. Homer recalls the judgement of Paris only once, in the last book of the Iliad, and mentions neither Eris nor the apple. Eris starting a quarrel at the wedding appears in the summary of the Cypria, and the apple appears in later writers such as Apollodorus and Hyginus.

Is Eris only an evil goddess?

No. In Works and Days Hesiod writes that there are two Erises. One fosters war, and the other makes people compete and drives them to work. The Theogony describes only her dark side.

Does Eris have rulership in classical astrology?

No. It is a dwarf planet found in 2005. In classical astrology domicile, exaltation, sect and joy belong to the seven traditional planets alone.

Why does Eris have two glyphs?

One is the Hand of Eris, which comes from the Principia Discordia and is the most widely used. The astrologer Henry Seltzer proposed the other in 2007. Unicode added both in 2018. This page uses the first.
