Darab Breaks the Roman Centre

From D2.5, Darab Fights the Roman Army. It illustrates D2.5.18–23:

D2.5.18
Then young Darab swept forward at full speed,And urged still faster on his mighty steed.
D2.5.19
No Roman champion dared withstand his hand;Their foremost lines collapsed across the land.
D2.5.20
He plunged, a wolf, into their center’s heart,And drove the mighty Roman ranks apart.
D2.5.21
Then wheeling to the right, he pressed the fight,And seized their arms and baggage in his might.
D2.5.22
He tore through Roman legions, rank by rank;No champion found safety on the flank.
D2.5.23
The men of Iran followed in his wake,Like lions rushing where the lines might break.
