APPLE OF DISCORD
This expression comes from Greek mythology. “This story begins at the wedding of the hero Peleus and the water-nymph Thetis, parents of the famous Achilles. All the gods are invited to the party, saving one: Eris, goddess of discord - an understandable omission. Eris, didn’t see it that way and resolved to get revenge.” She stole one of Hera’s golden apples and inscribed it “Property of the Fairest” and tossed it onto a banquet table “where it was squabbled over by every goddess on hand.”
