Gold Rings in the Onagers' Ears

From D10.18, Bahram’s Gur-e-Khar Hunt before the Princes. It illustrates D10.18.26–31:

D10.18.26
The troops behind him cleared the plain of game;Then Bahram gave command to mark his name.
D10.18.27
He bade them fashion rings of shining gold,And grave his royal name for all to hold.
D10.18.28
He ringed the creatures’ ears and let them go,That all the world his royal name might know.
D10.18.29
Three hundred beasts he loosed to range the waste,Each ringed, as royal quarry to be chased.
D10.18.30
A herald rode among the troops to say:“Give all these Gur-e-Khars as gifts away.
D10.18.31
Let merchants take them freely from the plain;Let no man sell his quarry here for gain.”
