Bijan Cleaves the Kaviani Standard

From B12.22, The Turanians Defeat the Iranians. It illustrates B12.22.69–75:

B12.22.69
But Fariborz, no friend to wisdom then,Cried: “Go away, rash youth among the men!
B12.22.70
You are too new to battle and too bold;The Shah gave me this standard to uphold.
B12.22.71
The army and the Pahlevan’s rank are mine;The throne and crown with my command combine.
B12.22.72
This standard is not yours by any right,Though none beneath the sky surpass your might.”
B12.22.73
Then Bijan drew his violet sword and boreIts edge against the standard that he tore.
B12.22.74
He split the standard straight across the seam,And seized one half beneath its violet gleam.
B12.22.75
He rushed out from the throng with furious speed,And bore the torn standard to his kin in need.
