harlequin (n.)

1580s, Harlicken, one of the stock characters of Italian commedia del'arte, from Middle French harlequin, from Italian arlecchino, which is possibly from the same source as Old French Herlequin, Hellequin, etc., leader of la maisnie Hellequin, a troop of demons who rode the night air on horses. This is perhaps of Germanic origin; he seems to correspond to Old English Herla cyning "King Herla," mythical character sometimes identified as Woden, and possibly also to German Erlkönig, the "Elf King" of the Goethe poem. Sometimes also associated with Herrequin, 9c. count of Boulogne, who was proverbially wicked. In English pantomime, a mute character who carries a magic wand. From his ludicrous dress comes the English adjective meaning "particolored" (1779).
