The Windfairies

The Windfairies was dedicated to the children of Margaret Burne-Jones who had heard the first stories.

There is less enchantment and more homeliness and moral purpose in these, but Dumb Othmar with Hulda's hallucinatory quest, accompanied by a glittering green snake, for her lover's lost voice has echoes of the supernatural world of Hoffman's The Golden Pot. (Goodreads)
