Argus Panoptes
Though the town is known to date to ancient times, during the Renaissance fanciful etymologies were invented to account for the place name "Montargis", whether as "mons argi", Mount of Argus, the place where the jealous goddess Juno charged Argus Panoptes with guarding her rival Io, or connected with the chieftain Moritas mentioned by Julius Caesar, in his Gallic Wars.
