A Roman nobleman, Mirin, asks Caesar for the hand of his second daughter, Dilanjam, but, after the debacle of his first daughter marrying an (apparently) unworthy husband, the king demands that the suitor first perform some deed of prowess, in this case killing a wolf as large as and elephant, with horns and tusks. In despair, Mirin approaches Gushtasp, promising to serve him if he will kill the wolf for him. Gushtasp goes to fight the beast. He wounds it with arrows and the angered monster kills Gushtasp's horse. Gushtasp slays the beast with his sword. Mirin marries the princess.
[Note that some of the pictures show the dead horse, but others, mistakenly, show the horse still alive when the hero kills the beast.]
