Read the excerpt from Gilgamesh: A New English Version.

Then, from heaven, the voice of the god
called to Gilgamesh: "Hurry, attack,
attack Humbaba while the time is right,
before he enters the depths of the forest,
before he can hide there and wrap himself
in his seven auras with their paralyzing glare.
He is wearing just one now. Attack him! Now!"
