Thou wast all that to me, love, for which my soul did pine- a green isle in the sea, love, a fountain and a shrine, all wreathed with fairy fruits and flowers, and all the flowers were mine. ah, dream too bright to last! ah, starry hope! that didst arise but to be overcast! a voice from out the future cries, “on! on! ”- but o'er the past (dim gulf! ) my spirit hovering lies mute, motionless, aghast! for, alas! alas! me for me the light of life is over! “no more- no more- no more- ” (such language holds the solemn sea to the sands upon the shore) shall bloom the thunder-blasted tree or the stricken eagle soar! and all my days are trances, and all my nightly dreams are where thy grey eye glances, and where thy footstep gleams- in what ethereal dances, by what eternal streams. what theme of the poem does the final stanza reveal?
