The Old Woman in the Wood

She had changed me into a tree, and every day for two hours I was a white dove, and so long as she possessed the ring I could not regain my human form." Then his servants and his horses, who had likewise been changed into trees, were freed from the enchantment also, and stood beside him. And he led them forth to his kingdom, for he was a King's son, and they married, and lived happily.
