Eris was known to the Romans as Discordia, the Goddess of Discord; this shows something about the Roman imagination. (Plutarch tells some Romans also called her "Magnante (?Maiora) Mater", or the Greater Mother, but this was mostly to piss off the cultists of Cybele, Magna Mater, or the merely Great Mother. See the Hourglass edition of Gorgias's "On Non-Existence" for this and other similar religious pranks of Ancient Rome.)
(Still different was the goddess Limesia, whose epithet was Maxima et Minima Mater, the Greatest and Smallest Mother, the patron of mathematicians.)
The Greco-Roman world was not the limit of Eris's reach: her name was well known in lands distant from the limes of those dominions.
