Zal Burns the Simorgh's Feather

From C8.25, The Simorgh Comes to Rostam’s Aid. It illustrates C8.25.1–10:

C8.25.1
When all three fixed upon that bold design,Zal climbed a height beneath the starlight’s shine.
C8.25.2
Three censers full of fire he bore that night;Three watchful, valiant men climbed to the height.
C8.25.3
Upon the summit, spell-wise Zal now stayed,And drew the feather from its rich brocade.
C8.25.4
He lit a censer’s fire amid the gloom,And burned a portion of the Simorgh’s plume.
C8.25.5
A watch of that dark night had passed; on highA cloud as black as iron filled the sky.
C8.25.6
The bird looked down from heaven toward the height,And saw the fire below her burning bright.
C8.25.7
Zal sat before it, sunk in grief and woe;The troubled bird came down to earth below.
C8.25.8
Zal came before her, aloeswood to bear,And offered praise and bowed his head in prayer.
C8.25.9
He filled three censers with their fragrant store;Down both his cheeks his liver’s blood would pour.
C8.25.10
The Simorgh said, “O king, what grief or fearHas made you burn my plume to call me here?”
