Siavash's Dream of Fire and Water

From B9.51, Siavash Is Troubled by a Dream. It illustrates B9.51.8–12:

B9.51.8
I saw a river stretching far and wide,A fiery mountain rose on the other side.
B9.51.9
And spearmen lined the water’s edge in rows,Along the bank their ordered ranks arose.
B9.51.10
On one side raged a fire both fierce and high,That burned Siavash-Gard beneath the sky.
B9.51.11
Thus fire and water hemmed me in from flight,Afrasiab and his elephant in sight.
B9.51.12
He watched me with a grim and hostile face,And blew upon the flames around that place.”
