Rostam's Gorz Fells Sava

From B14.12, Rostam Battles Sava. It illustrates B14.12.21–29:

B14.12.21
Then Sava, proud kinsman of Kamus, came,With high ambition none could curb or tame.
B14.12.22
An Indian sword was ready in his hand;He came to fight where Rostam took his stand.
B14.12.23
He circled to the left, then to the right,And sought revenge for Kamus in the fight.
B14.12.24
“O mighty elephant,” he cried, “now markA Nile-wave rising, terrible and dark.
B14.12.25
I shall avenge Kamus; this fight shall beThe last such battle you shall ever see.”
B14.12.26
When Sava’s words reached Rostam in the fray,He drew his heavy gorz without delay.
B14.12.27
He struck the warrior’s head with all his might;In agony, his spirit took its flight.
B14.12.28
He rode his Rakhsh across him on the ground;Of Sava, not a trace could then be found.
B14.12.29
The Kashani standard tumbled to the plain;The army’s heart was wrung with fear and pain.
