Discord, The Goddess of, a mischief-making divinity, daughter of Night and sister of Mars, who on the occasion of the wedding of Thetis with Peleus, threw into the hall where all the gods and goddesses were assembled a golden apple inscribed “To the most Beautiful,” and which gave rise to dissensions that both disturbed the peace of Olympus and the impartial administration of justice on earth. See Paris.
