from his father's garden. He then goes on a quest for a golden-maned horse and the Prettiest Princess in the World, with the help of a fox. At the end of the tale, the fox is revealed to be the princess's brother. Mexico J. Alden Mason collected a variant from Mexico, titled Cuento del Pájaro del Dulce Canto (English: "The Bird of the Sweet Song"). Brazil In a Brazilian variant collected by Sílvio Romero in Sergipe, A Raposinha (English: "The little fox"), a prince stops three men from beating a dead person, and in gratitude is helped by a fox in his search for a parrot from the Kingdom of Parrots as a cure for the king's blindness. Literary versions French author Edouard Laboulaye included a literary version named The Three Wonders of the World in his book Last Fairy Tales: the queen wishes for a magical bird that can rejuvenate people with its song. The youngest prince also acquires the winged horse Griffon and a wife for himself, the princess Fairest of the Fair. Italian author Luigi Capuana used the motif of the golden-coloured bird stealing the apples in his literary fiaba Le arance d'oro ("The Golden Apples"), where a goldfinch is sent to steal the oranges in the King's orchard.Capuana, Luigi. Once upon a time fairy tales. New York: Cassell Publishing Company. 1893. pp. 16–28. Professor Jack Zipes states that the tale type inspired Russian poet Pyotr Pavlovich Yershov to write his fairy tale poem The Little Humpbacked Horse. The tale begins akin to ATU 530, "The Princess on the Glass Mountain", (hero finds or captures wild horse(s) with magical powers) and continues as ATU 550: the envious Tsar asks the peasant Ivan to bring him the firebird and the beautiful Tsar-Maid. A literary treatment of the tale exists in The True Annals of Fairy-Land: The Reign of King Herla, titled The Golden Bird: with the help of friendly fox, the king's youngest son ventures to seek the Golden Bird, the Golden Horse and a princess, the Beautiful Daughter of the King of the Golden Castle. At the conclusion of the tale, the fox is revealed to be the Princess's brother, transfomed into a vulpine shape. Czech school teacher Ludmila Tesařová (cs) published a literary version of the tale, named Pták Zlatohlav, wherein the knight quests for the golden-headed bird whose marvellous singing can cure an ailing princess.
