The Three Treasures of the Giants is a Slavonic fairy tale collected by Louis Léger in Contes Populaires Slaves.
After he died, the sons set out to seek their fortune; the older two wanted to leave the youngest behind, but their mother said there was nothing for him there.
The youngest son used the trumpet and the king offered to give back the table and let him marry the princess.
In Lang's variant, the youngest son lived to be old and happy, but his descendants were too proud to look after the treasure and so were overcome.
In Manning-Sanders's, the hermits arrived and demanded the table; because they could not both take it to their hermitages, the princess proposed that they remain at the castle and eat there every day.
