Eris

In Greek mythology, the personification of strife, companion of the war-god Ares and a daughter of Night (Nyx). She was known to the Romans as Discordia.

In later tradition, Eris was held responsible for the Trojan wars. Angered by her exclusion from the wedding of Peleus and Thetis, she had flung the golden apple of discord among the guests. Possession of the apple, which was inscribed ‘to the fairest’, was hotly disputed by the goddesses Hera, Aphrodite, and Athena. The ‘judgement of Paris’, given by the Trojan prince to Aphrodite, set off a rivalry between the three goddesses played out in the Trojan wars.
