Giv Plants the Royal Letter on the Wall

From B10.35, Kay Khosrow Captures Bahman Castle. It illustrates B10.35.25–34:

B10.35.25
Then Khosrow took a long and mighty spear,And bound the royal letter, plain and clear.
B10.35.26
He raised it like a standard in the air,And sought no prize but royal farr to bear.
B10.35.27
He called to Giv and gave him this command:“Take up this spear and do as I have planned.
B10.35.28
Bear forth this letter, stern in warning, high,And bring it where the rampart meets the sky.
B10.35.29
Invoke Yazdan, then turn your reins away;Do not remain beside the wall or stay.”
B10.35.30
Then faithful Giv, with blessings, rode to fight,The spear in hand, toward the fortress height.
B10.35.31
Through Khosrow’s farr he fixed it in the wall,The royal letter set beyond recall.
B10.35.32
He praised Yazdan, the giver of the good,Then wheeled his white horse swiftly as he could.
B10.35.33
The famous letter vanished; in its steadA crash rose up, and dust above it spread.
B10.35.34
By Yazdan’s high command the rampart split,Its mighty wall was torn from where it knit.
