Rakhsh Kills the Lion in the Reeds

From B5.1, Rakhsh Fights a Lion. It illustrates B5.1.14–20:

B5.1.14
One watch had passed; the lion neared his bed,And saw brave Rakhsh beside the sleeper’s head.
B5.1.15
He saw the steed, and Rostam sleeping sound,An elephantine body, like a mound.
B5.1.16
“First crush the horse,” he thought, “and clear my way;The sleeping man will then become my prey.”
B5.1.17
He sprang; but Rakhsh, like fire, rose in flame,And charged the lion as the lion came.
B5.1.18
He struck its head with both forelegs in rage,Then seized its back, his sharpened jaws a cage.
B5.1.19
He smashed the lion hard against the ground,And tore it till no trace of life was found.
B5.1.20
Then Rostam woke and saw the lion slain,Its shattered body stretched across the plain.
