The Paladins Perish in the Snow

From C4.63, The Pahlevans Are Lost in the Snow. It illustrates C4.63.20–28:

C4.63.20
They ate the food still left them from the day;Then soon in sleep the weary warriors lay.
C4.63.21
Then wind arose and clouds obscured the sky,Which took the aspect of a lion’s eye.
C4.63.22
The snow unfurled its sail of blinding white;Across the plain, each lance was lost to sight.
C4.63.23
A heavy, raging snowfall swept around,And leveled all the wide expanse of ground.
C4.63.24
The helpless heroes perished in the snow: Tus, Gostaham, and Fariborz lay low;
C4.63.25
With valiant Giv and young Bijan, they passed, Enclosed within that frozen tomb at last.
C4.63.26
One after one, the snow closed round them deep;I cannot tell how long that grip would keep.
C4.63.27
They struggled for a while beneath the storm;Deep hollows in the ground began to form.
C4.63.28
No strength remained to struggle or to strive;Their souls departed; none was left alive.
