The Three Enchanted Princes is an Italian literary fairy tale written by Giambattista Basile in his 1634 work, the Pentamerone.[1]
The king of Green Bank had three beautiful daughters. The king of Fair Meadows had three sons, who had been transformed into a falcon, a stag, and a dolphin; these sons loved the three daughters, but the king would not marry them to animals. The sons summoned all the animals of their kind and made war until the king yielded. They were married, and the queen gave each of her daughters a ring so they could recognize one another.
After the wedding, the queen gave birth to a son, Tittone. One day, she lamented that she never heard what happened to her daughters. Tittone set out to find them. He found the eldest with the falcon husband; she hid him and persuaded her husband to let him visit. He stayed for a time, and the falcon gave him a feather when he set out to find the other sisters. After a time, he found the second sister, and her husband the stag made him welcome, and when he left, gave him some of its hair. He found the third husband, and her husband the dolphin made him welcome and gave him some scales when he left.
Returning, he found a maiden captive in a tower, where a dragon slept, and which was surrounded by a lake. She begged him to save her. He threw down the feather, hairs, and scales, and his brothers-in-law appeared. The falcon summoned griffins to carry her to freedom; when the dragon woke, the stag summoned lions, bears, and other animals to tear it to pieces; the dolphin had waves engulf the tower to destroy it. This freed the brothers-in-law from their enchanted shapes, and they returned with their brides to their own parents, and Tittone returned to his with his bride.
