      Enkidu ate grass in the hills with the gazelle and lurked with wild beasts at the water-holes; he had joy of the water with the herds of wild game. But there was a trapper who met him one day face to face at the drinking-hole, for wild game had entered his territory. On three days he met him face to face, and the trapper was frozen with fear. He went back to his house with the game that he had caught and he was dumb, benumbed with terror. His face was altered like that of one who has made a long journey. With awe in his heart he spoke to his father: 'Father, there is a man, unlike any other, who comes down from the hills. He is the strongest in the world, he is like an immortal from heaven. He ranges over the hills with wild beasts and eats grass; he ranges through your land and comes down to the wells. I am afraid and dare not go near him. He fills in the pits which I dig and tears up my traps set for the game; he helps the beasts to escape and now they slip through my fingers.'
