To the ancient Greeks, Eris was the winged goddess of discord and contention. Her Roman equivalent was Discordia. This is a picture of a
Athenian black figure kylix c. 6th century BCE Even the other gods didn't like the disagreeable Eris. She was the only one of the gods that didn't get invited to the wedding of Peleus and Thetis. Angered at this, she managed to initiate a quarrel amongst the goddesses that set in train the events that led to the Trojan War. Fortunately, despite the disagreement amongst astronomers that followed the discovery of the dwarf planet Eris, it wasn't on the scale of the Trojan War.
