In celebration of the marriage of Peleus and Thetis, Lord Zeus, father of the Greek pantheon, hosted a banquet on Mount Olympus. Every deity and demi-god had been invited, except Eris, the goddess of strife (no one wanted a troublemaker at a wedding). For revenge, Eris threw the golden Apple of Discord inscribed with tēi kallistēi - For the most beautiful - into the party, provoking a squabble among the attendant goddesses over for whom it had been meant.
