What are some symbols in "Richard Cory"?

I
believe the main symbolic image in this poem ishimself.  He symbolizes fame and fortune.  The
poem's narrator directly tells readers that Richard Cory was wealthy beyond imagination.
 

And he was richyes, richer than a king

Additionally, Richard Cory is schooled in perfect social graces,
and physically fit.

He was a gentleman from sole to
crown,

Clean favored, and imperially slim.

He is who everybody wants to be.  He's the town celebrity that
makes everybody stare as he passes by and stutter when he talks to them.  Richard Cory is
revered like a king.  

 

Richard Cory is not a king, but he essentially symbolizes that role to the people of
the town.  It's why the narrator uses so many kingly and royal words to describe Richard Cory.
 Words like "crown," "imperially," "glittered," and
"king" are all used to describe Richard Cory.  

 

What I find most interesting about Richard Cory as a kingly symbol of wealth is that
the symbolism teaches a very cautionary message.  Richard Cory is so wealthy and graceful, and
the townspeople are in such awe of him that Richard Cory is an incredibly lonely and distanced
person.  Readers are told that Cory makes huge efforts to be treated like a regular member of
the town.  He goes to town, doesn't dress fancy, and talks about normal topics.  He's trying to
engage the people of the town, yet they never quite accept him; therefore, he's lonely.
 Eventually, he commits suicide to end his loneliness; therefore, I also see Richard Cory's
wealth as symbolic of depression and loneliness.  His money simply couldn't buy him happiness
and acceptance.
