Eris (Greek Ἔρις, "Strife") is the Greek goddess of strife,
her name being translated into Latin as Discordia. Her 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 for the
（*)/Eris), the goddess who calls forth war and discord.
According to the Iliad, she wanders about, at first small and
insignificant, but she soon raises her head up to heaven
(4.441). She is the friend and sister of Ares, and with him
she delights in the tumult of war, increasing the moaning of
men. (4.445, 5.518, 20.48.) She is insatiable in her desire
for bloodshed, and after all the other gods have withdrawn
from the battle-field, she still remains rejoicing over the
havoc that has been made. (5.518, 11.3, &c., 73.) According to
Hesiod (Hes. Th. 225, &c.), she was a daughter of Night, and
the poet describes her as the mother of a variety of
allegorical beings, which are the causes or representatives of
man's misfortunes. It was Eris who threw the apple into the
assembly of the gods, the cause of so much suffering and war.
[PARIS.] Virgil introduces Discordia as a being similar to the
Homeric Eris; for Discordia appears in company with Mars,
Bellona, and the Furies, and Virgil is evidently imitating
Homer. (Aen.. 8.702; Serv. Aen. 1.31, 6.280.) - A Dictionary
