Darab Breaches the Lake

From D3.1, Darab Builds the City of Darabgird. It illustrates D3.1.18–22:

D3.1.18
As he passed from the lowlands toward the height,A deep and boundless lake appeared in sight.
D3.1.19
From India and the western Caesar’s lands,He summoned men of proven skill in bands.
D3.1.20
They were to seek a passage for the tide,And send a river forth to every side.
D3.1.21
A skilled man breached the barrier to the flow;The king decreed a thriving town should grow.
D3.1.22
And when the mighty outer wall was done,They named it Darabgird beneath the sun.
