The Washerman Finds Darab with a Bow

From D2.2, Darab Is Raised by a Washerman. It illustrates D2.2.47–53:

D2.2.47
He found him practicing the bow, intent,And all his long, hard searching was well spent.
D2.2.48
A thumbstall fitted tightly on his hand;With chest spread wide, he took an archer’s stand.
D2.2.49
He took the bow and spoke in accents cold,“You troublesome, contentious child so bold!
D2.2.50
Why do you hunger after bow and dart?Why nurse mistrust so young within your heart?”
D2.2.51
Darab replied, “O father, why obscureMy flowing water, which was clear and pure?
D2.2.52
First send me to the teachers skilled and wise,To learn the lore that they so greatly prize.
D2.2.53
Once I have learned the Zand-Avesta’s lore,Then name my trade; ask nothing else before.”
