Please interpret the following quotation from The Odyssey."Always I had in mind some giant, armed in giant force would come against me here. But...

This quote by Polyphemus, the Cyclops, to Odysseus is
classic situational irony in which the giant admits to
being defeated by a mortal.

The Cyclops arrogantly
underestimates his opponent.  As a giant with massive strength he naturally assumes his
nemesis to be a giant with massive strength.  Goliath overestimates himself
here.

The situation is an
analogy, a kind of retelling of the end of the Trojan War
in which Odysseus, through his cunning, burned Troy to the
ground with a wooden horse.  They too expected to be defeated by a giant armed force.
 Instead of a horse, Odysseus uses a little wine to disarm the giant and gouge his eye.
 It's not the first time in literature that wine and blood have been used in this
cause-effect fashion.

The conciliation is filled with
Homeric epithets (nicknames) when Cyclops calls Odysseus
"you--small, pitiful and twiggy."  It shows conflict between the mortal and immortal in
which Homer, a humanist, champions mankind.

And it reflects
one of the great themes in literature: blindness.  Physical
blindness is always an indiction of moral blindness.   The Cyclops is being punished for
hubris and living with no law.
