Bahram Chubin Prostrate Before Battle

From E5.11, Bahram Chubin Slays King Saveh. It illustrates E5.11.41–47:

E5.11.41
Then Bahram, when his ranks were set in place,Withdrew from camp and fell upon his face.
E5.11.42
Before his God, he cried aloud in dust,“O righteous Judge, whose every doom is just,
E5.11.43
If this my conflict is unjust to You,And Saveh’s cause is truer in Your view,
E5.11.44
Then calm my heart within this battle’s roar,And grant him triumph over us in war.
E5.11.45
But if I toil and strive at Your command,And risk my head in battle as I stand,
E5.11.46
Make me and all my troops rejoice in peace;Let warfare’s torment through the whole world cease.”
E5.11.47
Still praying loudly, he arose foursquare,His ox-head gorz raised high in morning air.
