Rakhsh Bites the Dragon

From B5.3, Rostam Fights a Dragon. It illustrates B5.3.36–43:

B5.3.36
The dragon grappled fiercely in the fray,But from Tahamtan found no path away.
B5.3.37
It battled him with overwhelming might,And Rakhsh beheld his master pressed in fight.
B5.3.38
But seeing Rostam hard beset and near,He rushed upon the beast and cast off fear.
B5.3.39
He laid his ears back, sprang as lions would,And bit the towering dragon where it stood.
B5.3.40
He tore its shoulder with his sharpened teeth,Like lion’s jaws that rend the flesh beneath.
B5.3.41
At Rakhsh’s deed great Rostam stared amazed,To see his steed against the dragon raised.
B5.3.42
Then Rostam struck with one resounding blow;His flashing blade laid low the monstrous foe.
B5.3.43
The severed head fell crashing to the plain,And blood poured forth like rivers after rain.
