Barbad Bows Before Khosrow

From E7.6, The Minstrels Sarkash and Barbad. It illustrates E7.6.59–66:

E7.6.59
When Barbad heard the monarch’s gracious call,His fear dissolved; he chose to answer all.
E7.6.60
He climbed down from the cypress, glad of heart,And came before the king who praised his art.
E7.6.61
He placed his face upon the dust, bowed low;The king said, “Speak! Who are you? Let me know.”
E7.6.62
He answered, “Shah, I am your slave, and liveOnly by what your voice and throne can give.”
E7.6.63
He told the king his story from the start,And all that he had borne in flesh and heart.
E7.6.64
The king rejoiced to see him, as the roseRejoices when the springtime wind first blows.
E7.6.65
He turned to Sarkash: “You have earned disgrace;Beside his sweetness, gall is in your place.
E7.6.66
Why did you bar his entrance to my hall,And grudge his music to us, one and all?”
