One Arrow Through Four Shields

From B9.46, Siavash Shows His Skill at Polo. It illustrates B9.46.25–30:

B9.46.25
Four shields of Gilan Siavash ordered then,Two wood, two tempered steel before the men.
B9.46.26
He took six poplar arrows at his waist,One shaft in hand, its feathered end well placed.
B9.46.27
He set one arrow ready on the string,And drew the bow until it formed a ring.
B9.46.28
He loosed; one shaft pierced every shield in line,And all the watching ranks beheld the sign.
B9.46.29
Three further arrows followed on its track,Each pierced the shields and none was driven back.
B9.46.30
Old men and youths cried out in wonder loud,And called on Yazdan through the gathered crowd.
