goddess of discord, from Greek eris "strife, discord," of uncertain origin. Related: Eristic.
/e'ris/ The Greek goddess of Chaos, Discord, Confusion, and Things You Know Not Of; her name was latinised to Discordia and she was worshiped by that name in Rome. Not a very friendly deity in the Classical original, she was reinvented as a more benign personification of creative anarchy starting in 1959 by the adherents of Discordianism and has since been a semi-serious subject of veneration in several "fringe" cultures, including hackerdom.
