E6.27.13
When thirst had parched their mouths, they sought and foundAn aging woman’s house on humble ground.
E6.27.14
In courteous words they asked for drink and bread;She brought an ancient sieve and on it spread
E6.27.15
A piece of waterskin, and on it laidThe barley bread, a humble meal she made.
E6.27.16
Yalan-sina gave barsom for the prayer;Bahram forgot the words in his despair.
E6.27.17
They ate, then asked for wine to crown the board;The woman said she had a little hoard.
E6.27.18
“I have an ancient gourd, its top cut through;I made a cup and set it here for you.”
E6.27.19
Bahram replied, “Then fill that rustic cup;No finer vessel could be lifted up.”
E6.27.20
She fetched the wine; he drank and was content,And to the crone a brimming portion sent.
E6.27.21
“Take cheer too, gracious mother; tell me, say,What tidings move the world about today?”
E6.27.22
“My brain is worn,” she said, “from all I hear;Today men came from town; their news was clear.
E6.27.23
They said Bahram’s troops joined the Shah instead;Their chief escaped without them when he fled.”
E6.27.24
He asked, “Did Bahram act as wisdom taught,Or choose the pleasure his desires had sought?”
