Read the excerpt from “to one in paradise,” by edgar allan poe. thou wast all that to me, love . . a fountain and a shrine, all wreathed with fairy fruits and flowers, and all the flowers were mine. how does poe use a sound device in the excerpt? he uses assonance to connect the images of architecture. he uses alliteration to draw attention to the images of his love. he uses cacophony to create a discordant sound of loss. he uses internal rhyme to enhance the rhythm of his lyrical poem.
