Eris

In Greek mythology, Eris is the goddess and personification of strife and discord, particularly in war, and in the Iliad. According to Hesiod she was the daughter of primordial Nyx (Night), and the mother of a long list of undesirable personified abstractions, such as Ponos (Toil), Limos (Famine), Algea (Pains) and Ate (Delusion). Eris initiated a quarrel between Hera, Athena and Aphrodite, which led to the Judgement of Paris and ultimately the Trojan War. Eris's Roman equivalent is Discordia. According to Hesiod, there was another Eris, separate and distinct from Eris the daughter of Nyx, who was beneficial to men.
