What are two poetic devices presented in the poem "Richard Cory," that helped to enhance the poet's work.

Here's the
poem:

Wheneverwent down town, 
We people on the
pavement looked at him: 
He was a gentleman from sole to
crown, 
Clean-favoured and imperially slim. 

And he was always
quietly arrayed, 
And he was always human when he talked; 
But still he
fluttered pulses when he said, 
"Good Morning!" and he glittered when he
walked. 

And he was rich, yes, richer than a king, 
And admirably
schooled in every grace: 
In fine -- we thought that he was everything 
To
make us wish that we were in his place. 

So on we worked and waited for the
light, 
And went without the meat and cursed the bread, 
And Richard Cory, one
calm summer night, 
Went home and put a bullet in his head.

Henry David Thoreau said "men live lives of quiet
desperation."  None more than Richard Cory, it seems, whose suicide is not necessarily a
shock to those in the town, but rather a source of morbid fascination and gossip.

The poem appears simple, straightforward, and
conventional: there is no , no , no symbolism, no lyric self-expression.

Rather, the key is the speaker's tone: he is a reporter
giving us the news.  The poem reads like an obituary.  It confirms what all the townspeople
already know, but it seals Cory's death in black and white print for posterity--a detached
epitaph for the ages.

The two key poetic devices
are  and humor which relies on the
contrast between the image of Cory's stoic exterior  and the violence of his death.  If a longer
piece, the poem would be Horatian , .

Critic Ellsworth Barnard says it
best:

The first two lines suggest Richard Cory's
distinction, his separation from ordinary folk. The second two tell what it is in his natural
appearance that sets him off. The next two mention the habitual demeanor that elevates him still
more in men's regard: his apparent lack of vanity, his rejection of the eminence that his
fellows would accord him. At the beginning of the third stanza, "rich" might seem to
be an but not inthe eyes of ordinary Americans; though, as the second line
indicates, they would not like to have it thought that
in their eyes wealth is everything. The last two lines of the stanza record
a total impression of a life that perfectly realizes the dream that most men have of an ideal
existence; while the first two lines of the last stanza bring us back with
bitter emphasis to the poem's beginning, and the impassable gulf, for most peoplebut not, they
think, for Richard Corybetween dream and fact. Thus the first fourteen lines are a painstaking
preparation for the last two, with their stunning overturn of the popular belief.
