Idylls are short, descriptive poems or prose pieces that depict peaceful, idealized scenes of rural life or nature. They often celebrate the beauty of the countryside and the simplicity of pastoral living, focusing on themes such as love, harmony, and the joys of nature. The term is commonly associated with the works of poets like Alfred Lord Tennyson, who wrote a series of poems titled "Idylls of the King," which explore the legends of King Arthur and his knights. These works blend idyllic imagery with deeper moral and philosophical themes, reflecting both the beauty and complexity of life.
