Siavash's Last Prayer

From B9.55, Siavash Falls by Gurvi’s Hand. It illustrates B9.55.3–14 (to B9.55.15):

B9.55.3
He seized his hair and dragged him through the dust,While Siavash raised his voice in prayer and trust:
B9.55.4
“O Lord beyond all place, all time, all change,Let not my line be lost in lands so strange.
B9.55.5
Let from my seed a radiant branch arise,A son whose glory shines beneath the skies.
B9.55.6
Let him avenge the wrongs that here are done,And make my name renewed beneath the sun.
B9.55.7
Beneath his feet let all the world be laid,And let true manhood through his deeds be displayed.”
B9.55.8
Behind them Pilsam followed, sick with dread,His eyes ran blood; his grieving heart seemed dead.
B9.55.9
The prince cried out: “Farewell; go with my prayer,And take to Piran word of my despair.
B9.55.10
Go speak to Piran; tell him what you see:‘The world has turned from all it promised me.
B9.55.11
My hope in Piran scattered, fled, and died;Like willow now I tremble, terrified.
B9.55.12
He promised horsemen, armored rank on rank,A hundred thousand strong upon my flank,
B9.55.13
To stand beside me when my fortune turned,And aid me when the fires of danger burned.
B9.55.14
But now on foot before Garsivaz I go,Abased and dark of heart beneath this woe.
