Bijan Is Cast into the Pit under Akvan's Stone

From C2.10, Bijan Is Put in Bonds. It illustrates C2.10.1–12 (to C2.10.20):

C2.10.1
Afrasiab commanded: “Garsivaz, obey;Prepare a pit where light shall lose its way.
C2.10.2
Draw both his hands in chains, his throat in hold,And clamp a Rumi bond, bridge-arched and cold.
C2.10.3
Make all secure with heavy rivets fast,Then headfirst down to black despair be cast.
C2.10.4
Shut sun and moon forever from his eyes;Take elephants where Akvan’s great stone lies.
C2.10.5
That stone the Piltan raised from ocean deep,And cast in Chin’s far wilds for fate to keep,
C2.10.6
That stone shall now avenge me on this man;Bring elephants and all the force you can.
C2.10.7
The stone above Arzhang’s dark dungeon-doorShall seal him in and hide him evermore.
C2.10.8
Then leave him there to madness, grief, and night,And ride to Manijeh’s palace in your might.
C2.10.9
Go sack the palace of that wanton maid,Whose shameless choice has made her honor fade.
C2.10.10
Strip her of crown and fortune, head and all,And speak these words, and let my anger fall:
C2.10.11
‘Accursed, wretched girl, unfit to wearThe royal crown or breathe the royal air,
C2.10.12
You have abased my head among the great,And dragged my royal crown through scorn and hate.’
