The helmet which Pluto gave to the Cyclops made them invisible whenever it was worn.
The Moros Musphoron was a girdle of invisibility. (Mrs. Centlivre: A Bold Stroke for a Wife.
Otnit's ring. The ring of Otnit, King of Lombardy, according to the Heldenbuch, possessed a similar charm. Reynard's wonderful ring had three colours, one of which (the green) caused the wearer to become invisible. (Reynard the Fox, 1498.)
