Byron uses imagery in his poem to better describe the separation and sadness he experiences. "Pale grew thy cheek and cold, colder thy kiss," is a perfect example of this imagery. Byron is depicting the imagery of him and his love parting ways, detaching of emotions. "The dew of the morning sunk chill on my brow--" is another prime example of Byron's use of imagery. It is almost as if you can feel the cold dew yourself. Byron's use of imagery here completes the despairing tone about losing someone he loves. Lastly, "A knell to mine ear; A shudder comes over me," is another useful example of the poem's imagery. It creates this funeral feeling, moreover, explaining that his love died and his heart is broken.
Byron also uses symbolism in this poem to show how hurt he was. "In silence I grieve," shows just how secret his affair was. Since no one knew about his affair but himself and his lover, he could not grieve in public about the loss. Instead, he had to weep in the comfort of his own home. When Byron writes, "Thy spirit deceives," he is saying that since he can't grieve in public without people thinking things, he must try and act like nothing is wrong when he is not alone.
Byron's pattern of rhyme adds a certain strength to the poem. This strength, shown in his rhyming, truly makes the reader feel what the author was feeling. Not only is there rhythm in this poem, but there is also many examples of repetition. For example, Byron repeated the words "silence" and "tears" numerous times throughout his poem. This was to show how his affair and all of his feelings, along with his emotions, were silent. Meaning he did not discuss them with anyone, ever.
