Siavash Strings the Bow Garsivaz Could Not

From B9.33, Siavash Displays His Prowess before Afrasiab. It illustrates B9.33.59–68:

B9.33.59
The prince then took his Kayan bow, and raisedIt from its case before them as they gazed.
B9.33.60
The king then asked to see the mighty bow,And had a servant bring it forth to show.
B9.33.61
He took it, marveled at its strength and size,And praised the bow before the watching eyes.
B9.33.62
He gave it then to Garsivaz: “Now try,And bend and string this bow before my eye.”
B9.33.63
But all in vain; his utmost could not bringThat stubborn bow to bend, or brace the string.
B9.33.64
Siavash took it, bent it with his hand,And strung it smoothly, smiling where he scanned.
B9.33.65
The king declared: “Such bows demand the mightOf youthful arms to bend and string them right.
B9.33.66
In youth I too had strength; my arm was bold,But age has stolen it; I have grown old.
B9.33.67
No man in Iran or Turan, in war’s days,Could wield this bow and win such lasting praise.
B9.33.68
Save him whose chest and shoulders bear such might;No other arm could bend and string it tight.”
