Read the poem “To One in Paradise,” by Edgar Allan Poe.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 ariseBut to be overcast!A voice from out the Future cries,“On! on!”- but o'er the Past(Dim gulf!) my spirit hovering liesMute, motionless, aghast!For, alas! alas! meFor me the light of Life is over!“No more- no more- no more- ”(Such language holds the solemn seaTo the sands upon the shore)Shall bloom the thunder-blasted treeOr the stricken eagle soar!And all my days are trances,And all my nightly dreamsAre 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 third stanza reveal?
