Regret

There's a regret that from my bosom aye
  Wrings forth a dirgy sweetness, like a rain
  Of deathward love; that ever in my brain
Uttereth such tones as in some foregone way
Seem gathered from the harmonies that start
  Into the dayspring, when some rarest view
  Unveileth its Tempèan grace anew
To meet the sun—the great world’s fervent heart.
’Tis that, though living in his tuneful day,
  My boyhood might not see the gentle smile,
Nor hear the voice of Shelley; that away
  His soul had journeyed, ere I might beguile
In my warm youth, by some fraternal lay,
  One thought of his towards this may native isle.
