The Tale of Ivan Tsarevich and the Gray Wolf is a Russian fairy tale collected by a Russian Slavist and ethnographer Alexander Afanasyev.

A king's apple tree bore golden apples, but every night, one was stolen. Guards reported that the Firebird stole them. The king told his two oldest sons that the one who caught the bird would receive half his kingdom and be his heir. They drew lots to see who would be first, but both fell asleep; they tried to claim it had not come, but it had stolen an apple. Finally Ivan Tsarevich, the youngest son, asked to try; his father was reluctant because of his youth but consented. Ivan remained awake the entire time, and upon seeing the bird, tried to catch it by the tail. Unfortunately, Ivan only managed to grasp one feather. The Firebird did not return, but the king longed for the bird. He said that still, whoever caught it would have half his kingdom and be his heir...
