Cf. Payne, Arabian Nights, vol. v. p. 121, wherein the maid flies to "the Castle of Jewels." The man only gets there by the aid of birds and beasts, and it is the third and most skilful magician alone who summons a bird, which is the only one who knows the far-off place. In another story, vol. vii., p. 176, the maiden flies to the "islands of Wac."
Dasent, p. 212, it is "Whiteland," and an old pike knows where it is.
Vernaleken, p. 251, Moon and Sun do not know where the mysterious place is, but the wind does. See also "the Drummer," p. 289, where the bride flies to the "Crystal Mountain."
In the Lapp stories we find "Banka Castle" and "Bæive-kingdom," and in an Irish tale, "Grey Horn's Kingdom," as the mysterious land.
The three men (or women) to whom the forsaken husband goes occurs in the Lapp stories, "Bondesønnen," "Bæive Kongens Datter," and "Fattiggutten," Nos. 44, 45, and 46, Friis.
