Robert Burns was an 18th century Scottish poet known for his celebration of Scottish national identity and culture through his poems written in the Scottish dialect. His most famous work, "A Red, Red Rose," uses nature metaphors like a red rose and melodic tune to depict his eternal love, as seen through lines saying he will love his bonnie lass until natural events like seas drying up or rocks melting that will never happen. The poem expresses the speaker's deep love through similes and promises of undying devotion, even as he bids his love farewell for now with the promise to return.
