Rostam Kicks Aside Bahman's Boulder

From C8.8, Bahman Delivers Esfandiyar’s Message. It illustrates C8.8.11–17:

C8.8.11
He loosened from the height a flinty mass,And sent it roaring down the mountain pass.
C8.8.12
Zavareh saw it hurtling toward the ground,And heard the mountain thunder with its sound.
C8.8.13
He shouted, “Pahlevan, look to the height!A boulder hurtles down with deadly might!”
C8.8.14
But Rostam neither moved nor set asideThe wild ass, while Zavareh loudly cried.
C8.8.15
He waited till the stone had thundered low,While dust rose thick and dimmed the daylight’s glow.
C8.8.16
Then with one kick he drove the boulder wide,While son and brother praised him at his side.
C8.8.17
Bahman felt sick at heart at what was done,And marked his majesty beneath the sun.
