Siavash's Farewell to Behzad

From B9.52, Siavash’s Farewell to Farangis. It illustrates B9.52.39–45:

B9.52.39
He sought the stables of his noble steeds,And led out Behzad, famed for battle deeds.
B9.52.40
Night-colored Behzad, swifter than the gale,On vengeance day would leave the wind to fail.
B9.52.41
He groaned and pressed its head against his breast,Then loosed its bridle, halter, gave it rest.
B9.52.42
He whispered counsel softly in its ear:“Stay wakeful-hearted; let no steed draw near.
B9.52.43
When Kay Khosrow shall rise to seek redress,Give him your reins and bear him through the press.
B9.52.44
Leave now the stable; break from every chain,For you shall bear him on the vengeful plain.
B9.52.45
Carry him forth; let terror spread ahead,And with your hoof sweep every foe in dread.”
