Khosrow in Siavash's Garden

From C4.33, The Shah’s Answer to Khosrow. It illustrates C4.33.26–30:

C4.33.26
So on he went; his tears and sorrow grewUntil his father’s city came in view.
C4.33.27
He walked Siavash’s garden and surveyedThe place where once the killer’s bowl was laid.
C4.33.28
From there he turned and went back to his throne,And spoke to God in secret, in low tone.
C4.33.29
“If God, the righteous Judge, will guide me through,And show the course that I must now pursue,
C4.33.30
I shall pour Afrasiab’s blood instead,Like water, here where Siavash once bled.”
