By definition, an archetype is of a very typical example of a certain kind of person or thing.
In literature, an archetype may be a character, a theme, a symbol, or even a setting.
Both 'the cyclops' and 'as a monster' are referring to characters. They also portray a certain kind of person or thing; a cyclops and a monster are both stereotyped as vicious and brutal.
