Analysis of Lines: The cold earth slept below

The cold earth slept below;
        Above the cold sky shone;
          And all around,
          With a chilling sound,
    From caves of ice and fields of snow
    The breath of night like death did flow
          Beneath the sinking moon.

The wintry hedge was black;
        The green grass was not seen;
          The birds did rest
          On the bare thorn's breast,
  Whose roots, beside the pathway track,
  Had bound their folds o'er many a crack
          Which the frost had made between.

Thine eyes glow'd in the glare
      Of the moon's dying light;
          As a fen-fire's beam
          On a sluggish stream
  Gleams dimly--so the moon shone there,
  And it yellow'd the strings of thy tangled hair,
          That shook in the wind of night.

The moon made thy lips pale, belov{`e}d;
      The wind made thy bosom chill;
          The night did shed
          On thy dear head
  Its frozen dew, and thou didst lie
  Where the bitter breath of the naked sky
          Might visit thee at will.
