Однако сюжет довольно четкий.

И точно не настолько древний.

Однако оказывается вот какие русские сказки бывают...

At that time Ivanoushka the Simpleton made up his mind to take a trip
somewhere. He put a saddle on a cow, jumped up on her back facing the
tail, and left the town. He came to a field, grasped the cow by the
horns, threw her far on the prairie and shouted:

"Come, come, you gray wolves and red foxes! there is a dinner for
you!"
