The Dragon and the Prince or The Prince and the Dragon is a Serbian fairy tale collected by A. H. Wratislaw in his Sixty Folk-Tales from Exclusively Slavonic Sources, tale number 43.
The oldest went hunting and chased a hare; when it fled into a water-mill and he followed, it turned into a dragon and ate him.
He took service as a shepherd with the emperor, who warned him not to go near the lake, though the sheep would go there if allowed.
They fought as before, but the emperor's daughter did kiss him, he threw the dragon into the air, and it burst when it hit the ground.
The pigeon told him that behind the water mill, three wands grew, and if he cut them and struck their root, he would find a prison filled with people.
