What would be an example of a metaphor, personification or a smilie in the story of the Cyclops?

A simile is when a writer compares one thing to another by
using the word "like" or "as."  You can see an example of a simile when Polyphemus the
cyclopes first grabs two of Odysseus's men and kills and eats them.  The narrator says
that the cyclopes

gripped up two of my men at once and dashed them
down upon the ground as though they had been
puppies

By comparing them to
puppies, the narrator is showing how little they were compared to the cycolpes.  He then
goes on to say that the cyclopes ate them as if he were a lion.  That's a simile too. 
He is comparing the cyclopes to a lion to show how vicious and ravenous he
is.
