[2] John Francis Campbell noted it as a parallel of the Scottish fairy tale, The Brown Bear of the Green Glen.

The dwarf told him it was in a castle, and gave him an iron wand to open the gates and two loaves to feed to the lions inside.

Treasure arrived, from the three kingdoms the youngest prince had saved, and the king wondered about his guilt and regretted having his son killed.

The princess in the castle had made a golden road to it and told her people that it would bring her true groom to her and to admit no one who did not ride straight up it.

The two older princes (who were pretending to be the ones who freed her) saw it and thought it would be a shame to get it dirty, so they rode alongside, and the servants did not admit them.

The tale is classified in the international Aarne-Thompson-Uther Index as type ATU 551, "The Water of Life" or "Sons on a Quest for a Wonderful Remedy for Their Father".

He sends his three sons to find and bring him the water, but they have first to pass through four obstacles, the last of which a castle where a maiden resides and holds the very keys to the fountain.

[10] At the end of the tale, the fairy maiden or foreign princess travels with her army or navy to the prince's kingdom in order to find the man who stole her wonderful bird or magical water.

The prince finds a brilliant golden feather on the way to another kingdom and delivers it to a second king, who wants the bird: the titular Kush-Pari.

To help them in their quest, they need their father's Fiery Horse, found in the depths of a forest, but only the youngest prince finds and rides it.

Some time later, she reveals her husband the location of the fabled lump of earth: at the bottom of a lake, guarded by "ferocious Watery Horses tall as Mares".

[18][19] W. A. Clouston saw the quest for the magical flower as a parallel to the German fairy tale "The Water of Life".
