The Epic of Gilgamesh
At twenty leagues they broke for some food,
at thirty leagues they stopped for the night.
They arrived in Uruk-Haven.
Gilgamesh said to Urshanabi, the ferryman:
"Go up, Urshanabi, onto the wall of Uruk and walk around.
Examine its foundation, inspect its brickwork thoroughly—
is not (even the core of) the brick structure of kiln-fired brick,
and did not the Seven Sages themselves lay out its plan?
One league city, one league palm gardens, one league lowlands, the open area(?) of the Ishtar
three leagues and the open area(?) of Uruk it (the wall) encloses." (11.310-319)
