Analysis of In Memoriam A. H. H.: 121. Sad Hesper o'er the buried sun

Sad Hesper o'er the buried sun
        And ready, thou, to die with him,
        Thou watchest all things ever dim
    And dimmer, and a glory done:
    The team is loosen'd from the wain,
        The boat is drawn upon the shore;
        Thou listenest to the closing door,
    And life is darken'd in the brain.
    Bright Phosphor, fresher for the night,
       By thee the world's great work is heard
       Beginning, and the wakeful bird;
   Behind thee comes the greater light:

The market boat is on the stream,
       And voices hail it from the brink;
       Thou hear'st the village hammer clink,
   And see'st the moving of the team.

Sweet Hesper-Phosphor, double name
       For what is one, the first, the last,
       Thou, like my present and my past,
   Thy place is changed; thou art the same.
