Houman Scouts Rostam's Pavilion at Dawn

From B13.27, Iran and Turan Set Their Battle Lines. It illustrates B13.27.4–15 (to B13.27.16):

B13.27.4
Houman the chief went forth to scan each side,And thought what aid the Iranians might hide.
B13.27.5
“What force has come with tents across the plain,Pavilions, camp-walls, standards in its train?”
B13.27.6
He saw a turquoise tent of diba made,With many attendants round its brocade shade.
B13.27.7
Before it stood a chief’s bright flag and spear;He thought that Fortune now had shifted here.
B13.27.8
He saw another army’s camp nearby,Its moon-bright standards gleaming in the sky.
B13.27.9
There Fariborz, the son of Kavus, stayedNear Tus, with elephants and koust arrayed.
B13.27.10
Houman went troubled to Piran and said,“Today will bring us bitter toil and dread.
B13.27.11
The Iranian clamor through the night was high,And louder than before it struck the sky.
B13.27.12
So I rode out alone at break of day,And scanned the foe’s encampments in array.
B13.27.13
A mighty force from Iran has drawn near,To aid their army in the battle here.
B13.27.14
One green diba pavilion faced the field;A dragon-standard rose beside its shield.
B13.27.15
Around it Zabul shield-men formed in rings,With Kabul blades prepared for warlike things.
