Eris is the greek goddess of discord, chaos, and strife. Her name is the equivalent of latin Discordia, which means "discord". Eris' greek opposite is Harmonia, whose latin counterpart is Concordia. Homer equated her with the war-goddess Enyo, whose roman counterpart is Bellona. The dwarf planet Eris is named after the goddess, as is the religion Discordianism.

The most famous tale of Eris recounts her initiating the trojan war by causing the Judgement of Paris. The goddesses Hera, Athena, and Aphrodite had been invited along with the rest of Olympus to the forced wedding of Peleus and Thetis, who would become the parents of Achilles, but Eris had been snubbed because of her troublemaking inclinations.

She therefore (as mentioned at the Kypria according to Proclus as part of a plan hatched by Zeus and Themis) tossed into the party the Apple of Discord, a golden apple inscribed τῇ καλλίστῃ (ancient greek: tē(i) kallistē(i))  – "for the most beautiful one", or "to the fairest one", provoking the goddesses to begin quarreling about the appropriate recipient. The hapless Paris, prince of Troy, was appointed by Zeus to select the fairest goddess. The goddesses stripped naked to try to win Paris' decision, and also attempted to bribe him. Hera offered political power; Athena promised infinite wisdom; and Aphrodite tempted him with the most beautiful woman in the world: Helen, wife of Menelaus of Sparta. While greek culture placed a greater emphasis upon prowess and power, Paris chose to award the apple to Aphrodite, thereby dooming his city, which was destroyed in the war that ensued.

Modern Worship[]

Eris is the patron god of the modern religion of Discordianism, a religion and subsequent philosophy based upon the veneration or worship of Eris, a.k.a. Discordia, the goddess of chaos, or archetypes or ideals associated with her. Discordianism was founded after the 1963 publication of its holy book, the Principia Discordia, written by Greg Hill with Kerry Wendell Thornley, the two working under the pseudonyms Malaclypse the Younger and Omar Khayyam Ravenhurst.

The religion has been likenned to Zen, based upon similarities with absurdist interpretations of the Rinzai school, as well as Taoist philosophy. Discordianism is centered on the idea that both order and disorder are illusions that are imposed on the universe by the human nervous system, and that neither of these illusions of apparent order and disorder is any more accurate or objectively true than the other.

She also figures in Greek Neopaganism, and certain varieties of Wicca.
