In "The Raven" by Edgar Allan Poe symbols and motifs is the device that plays a larger role. He uses it when he says " Uncertain rustling of each purple curtain thrilled me". It plays a large role because when you want to know the meaning of what the colors in the poem which its kind of a emotion or it tells a meaning of the poem.

In "The incident in the Rose Garden" by Donald Justice, alliteration is the device that plays a larger role. He uses it when he says"sir, you must be  that stranger who threatened my gardener. This is my property sir. I welcome only friends here". It plays a large role because not all stanzas rhyme so they need alliteration to make them make sense.
