Khosrow Led Away on the Elephant

From E7.11, Shiruyeh Sends Khosrow to Tisfoon. It illustrates E7.11.57–65:

E7.11.57
He said, “This armor now is earth to me,My golden shield the heaven I can see.
E7.11.58
The mountains are these garden treasures bright,That filled my heart, as lamps fill rooms with light.
E7.11.59
In truth my days are drawing to their end;Where is my star that once made worlds attend?
E7.11.60
Where are the peace and joy that once were mine?Where are the crowns on which my name would shine?”
E7.11.61
They brought an elephant; his soul was dark,And sorrow quenched in him its royal spark.
E7.11.62
He mounted, and the troops led him away;In Pahlavi he cried aloud that day:
E7.11.63
“O treasure, if you have become my foe,Be not a friend to those who bring me low.
E7.11.64
Today I stand in Ahriman’s command;You do not help me in this hostile land.
E7.11.65
Conceal yourself and show yourself to none;Let not my foes rejoice in what is done.”
