E3.2.81
Within the casket lie three pearls that shine,Enclosed beneath a covering rich and fine.
E3.2.82
One pearl is pierced, the second pierced halfway,The third has never known the iron’s way.”
E3.2.83
The Roman sage, on hearing, brought the keyTo Anooshirvan, that all the court might see.
E3.2.84
They opened it; a case lay wrapped insideIn silk that served the precious pearls to hide.
E3.2.85
Inside the silk three jewels shone intact,Confirming that the sage’s words were fact.
E3.2.86
The first was pierced, the second halfway through,The third was whole, as Bozorgmehr foreknew.
E3.2.87
The Mobadan praised him and let jewels rain;The king’s glad face shone bright, released from pain.
E3.2.88
He filled Bozorgmehr’s mouth with pearls of light,While shame oppressed his conscience at the sight.
