Ardeshir's Arrow and the Prince's Claim

From D6.4, Ardeshir Babakan and His Rival. It illustrates D6.4.44–53:

D6.4.44
A Gur-e-Khar appeared upon the plain;A clamor rose from all the hunting train.
D6.4.45
They urged their steeds; the dust rose thick and high,And mingled with the sweat as they sped by.
D6.4.46
Ardeshir rode ahead and neared the game,And set an arrow, taking careful aim.
D6.4.47
He struck the male Gur-e-Khar’s rump; straight throughIts body went the point and feathers too.
D6.4.48
Then Ardavan arrived upon the plain,And saw the fallen Gur-e-Khar lie slain.
D6.4.49
He asked, “Whose arrow felled this quarry grand?May life remain united with that hand!”
D6.4.50
Then Ardeshir addressed the king to say:“It was my arrow, Shah, that felled this prey.”
D6.4.51
One prince replied, “I brought it to its fate,And now I am in search of its own mate.”
D6.4.52
Ardeshir answered, “See, the plain is wide;With game and arrows here, let skill decide.
D6.4.53
Then strike another with the selfsame art;A lie brings shame upon a noble heart.”
