“When Lilacs Last in the Dooryard Bloom’d” is composed of three separate yet simultaneous poems. One follows the progress of Lincoln’s coffin on its way to the president’s burial. The second stays with the poet and his sprig of lilac, meant to be laid on the coffin in tribute, as he ruminates on death and mourning. The third uses the symbols of a bird and a star to develop an idea of a nature sympathetic to yet separate from humanity. The progression of the coffin is followed by a sad irony. Mourners, dressed in black and holding offerings of flowers, turn out in the streets to see Lincoln’s corpse pass by. The Civil War is raging, though, and many of these people have surely lost loved ones of their own. Yet their losses are subsumed in a greater national tragedy, which in its publicness and in the fact that this poem is being written as part of the mourning process, is set up to be a far greater loss than that of their own family members. In this way the poem implicitly asks the question, “What is the worth of a man? Are some men worth more than others?” The poet’s eventual inability to mourn, and the depictions of anonymous death on the battlefields, suggest that something is wrong here.
The poet vacillates on the nature of symbolic mourning. At times he seems to see his offering of the lilac blossom as being symbolically given to all the dead; at other moments he sees it as futile, merely a broken twig. He wonders how best to do honor to the dead, asking how he would decorate the tomb. He suggests that he would fill it with portraits of everyday life and everyday men. This is a far cry from the classical statuary and elaborate floral arrangements usually associated with tombs. The language in the poem follows a similar shift.
