Princess Rosette

[2] Italo Calvino included an orally collected tale, The King of the Peacocks, in his Italian Folktales, but observed in the notes that it was clearly a variant on Princess Rosette.

The nurse bribed the boatman to throw the princess, bed and all, with her little dog, into the sea in the middle of the night.

The bed was made of Phoenix feathers and floated, but the nurse put her own daughter in the princess's place.

An old man saw her on the shore and brought her to shelter, but saw by her possessions that she was a great lady, and he could only give her meager fare.

[6] The tale was one of many from d'Aulnoy's pen to be adapted to the stage by James Planché, as part of his Fairy Extravaganza.

[14] Princess Rosette is classified as Aarne–Thompson–Uther Index ATU 403, "The Black and the White Bride", tales where the female protagonist is substituted by a false heroine as the love interest.

The queen and her ladies-in-waiting consult with the hermit.
