Which poetic devices can be found in the poem "My Life Closed Twice Before its Close" by Emily Dickinson?

In Emily Dickinson's poem "My Life Closed Twice Before its Close," death is used as a metaphor for two events in the narrator's (poet's) life.

In Emily Dickinson's poem "My Life Closed Twice Before its Close," death is used as a metaphor for two events in the narrator's (poet's) life. We are not told what these events are, but they are surely tragic. The narrator feels as if she has died. If you do a bit of research, you will find that Dickinson lost two loved ones within a year of each other, so those losses may have been her inspiration for this poem.

The rhyme scheme in the poem is A, B, C, B in the first stanza and D, E, F, E in the second. This gives the poem a simple rhythm throughout.

Dickinson ponders actual physical death in comparison to the events suffered in life. Notice that the only capitalized word other than the first word in each line, is "Immortality," personifying the end of life or the beginning of what happens next.

Dickinson uses alliteration in the line, "So huge, so hopeless to conceive," repeating both the  primary "s" sound and the secondary "h" sound.

Finally, even the length of the poem may be an abstract allusion to the short time each of us has in this physical life of ours.
