Behind the scenes
Could possibly be in recognition of 'Alberich,' a powerful wizard from "Song of the Nibelungen." The poem is mythical, but was the basis for Wagner's Ring Cycle. In Wagner's version, Alberich makes a ring from gold that he has found and places a curse on it against its thief. Interestingly, one of the prizes given to a 'hero' of the Ring Cycle is an Invisibility Cloak.
