The Ram Leads Rostam to Water

From B5.2, Rostam Finds a Spring. It illustrates B5.2.11–18:

B5.2.11
Thus spoke the hero, faint with thirst and heat,Then sank upon the burning dust at his feet.
B5.2.12
His tongue was cracked, his breath had nearly flown,When sudden hope before his eyes was shown.
B5.2.13
A blessed ram moved lightly on the ground,Untouched by drought, in limb and body sound.
B5.2.14
Rostam beheld and thought: “This creature’s wayMust lead to water hidden from the day.
B5.2.15
In this I see the World-Creator’s grace;Some spring must lie beyond this burning place.”
B5.2.16
Through God’s own power he rose, though nearly dead,And followed where the blessed ram had led.
B5.2.17
With sword in hand, he held the reins drawn tight,And pressed ahead beneath the burning light.
B5.2.18
At last he reached the spring the ram had found,And life returned beside its waters’ sound.
