A few Rhinegold characters originate from outside the Eddas. Mime appears in the Thidriks saga, as a human smith rather than as an enslaved Nibelung. The three Rhinemaidens do not appear in any of the sagas and are substantially Wagner's own invention; he also provided their individual names Woglinde, Wellgunde and Floßhilde. In his analysis of "The Ring" Deryck Cooke suggests the Rhinemaidens' origin may be in the "Nibelungenlied", where three water sprites tease the characters Hagen and Gunther. Wagner may also have been influenced by the Rhine-based German legend of Lorelei, who lures fishermen on to the rocks by her singing, and by the Greek Hesperides myth in which three maidens guard a golden treasure.
