Explanation:

Elegies are narrative poems written after the death of a person. This poem acts as a means to mourn the death or passing of that person, and acts as a mournful song for the deceased.

Elegies are normally written in such a way that the beginning part expresses the pain and sorrow felt by the speaker at the death of the person. It then moves on to express consolation and comfort towards the end of the poem. Most famous elegies are "O Captain! My Captain!" by Walt Whitman written for Abraham Lincoln and W. H. Auden's "In Memory of W. B. Yeats".
