Dysnomia, imagined by Hesiod among the daughters of "abhorred Eris" ("Strife"), is the daemon of "lawlessness", who shares her nature with Atë ("ruin"); she makes rare appearances among other personifications in poetical contexts that are marginal to Greek mythology but become central to Greek philosophy. In a surviving fragment of Solon's poems, a contrast is made to Eunomia, a name elsewhere given to one of the Horae, the embodiments of order. Both were figures of rhetoric and poetry; neither figured in myth or Greek religious cult — although other personifications did, like Harmonia, "Agreement"; whether Harmonia is only a personification is debatable.
The dwarf planet Eris was discovered by the Palomar Observatory-based team of Mike Brown, Chad Trujillo, and David Rabinowitz on January 5, 2005, from images taken on October 21, 2003. The discovery was announced on July 29, 2005. It was originally called "Planet X" and nicknamed Xena after the character of the television program of the same name. Its then only known moon was called "Gabrielle" in honor of Xena's companion. Erisians (aka Discordians) Professor Mu-Chao with Reverend Loveshade began a campaign to get the planet named Eris or Discordia; this became known as "The Jake that Changed a World." The planet, re-classified as a dwarf planet along with Pluto, was named Eris on September 13, 2006 by the International Astronomical Union. The moon, named Shamlicht by Erisians, was officially named Dysnomia, the daemon of lawlessness. (This may have also been a reference to Xena who was played by Lucy Lawless).
