The metaphor adds to the passage the following:
. a description of the Cyclops’ eating habits
. a comparison between the Cyclops and a large land form
.a visual image of the Cyclops’ size
The Cyclopes are giant and huge creatures who were blessed by the Gods for food for their living. They don't want any visitors to come to their place. When Cyclops noticed that Odysseus and his men had arrived at his land, he captured them in his cave and treated them in the most inhospitable manner. He wanted to kill each of them but Odysseus tricked him and saved himself and his men from his captivity. The metaphor in the passage tells about the way the Cyclopes eat and the visual representation of their huge size.
