The Watchman Sees Rostam's Banners

From B13.21, Gudarz Hears of Rostam’s Coming. It illustrates B13.21.19–29:

B13.21.19
The Pahlevan then shed his bitter tears,And cried aloud before his gathered peers:
B13.21.20
“Saddle my steed; let brick now be my bed;From this day forth let brick support my head.
B13.21.21
I go once more to fill my eyes with friends,And clasp them close before our fortune ends.
B13.21.22
Shidush and Bijan, Rohham, Giv the bold,I will embrace while arms can clasp and hold.
B13.21.23
Those fiery warriors of noble breed,I will kiss their faces while my lashes bleed.”
B13.21.24
His gallant bay stood saddled at his side,When from the height the watchman loudly cried:
B13.21.25
“Rejoice, world-Pahlevan; let sorrow cease,For aid from Iran comes to bring release.
B13.21.26
A black dust rises on Iran’s road today,And darkens all the daylight on its way.
B13.21.27
Within its heart, bright standards fill the gloom,Like moons that rise above a battle’s plume.
B13.21.28
The first bears wolf-sign, fierce against the sky;The next displays the moon and rides on high.
B13.21.29
The third, a dragon with a lion’s head,In gold, is blazing where the banners spread.”
