Morozko is a Russian fairy tale collected by Alexander Afanasyev in Narodnye russkie skazki (1855-1863).
A woman has a daughter, whom she loves, and a step-daughter, whom she hates. One day, the woman orders her husband to take her stepdaughter out into the winter wilderness and to leave her there to die, and he obeys, leaving her at the foot of a tree in the forest. Father Frost finds her there, and because the girl is polite and kind to him, he gives her a chest full of beautiful jewels and fine garments. Some time later, the stepmother sends the girl's father to retrieve her body for burial, and is enraged when he instead brings the girl back alive and happy and dressed in finery. Consumed by greed and envy, the woman orders her husband to take her own daughter to the same place, but when found by Father Frost the woman's daughter is rude and unkind to him, and he is inclined to punish rather than reward her. The father finds her frozen to death at the foot of the tree and carries her body back to her grief-stricken mother.
