Theocritus was an ancient Greek poet, often considered the father of pastoral poetry. He lived during the 3rd century BCE on the island of Sicily. His works primarily focus on rural life, nature, and the beauty of the countryside, capturing the simplicity and charm of shepherds and their surroundings. Theocritus is best known for his collection of poems called Idylls, which depict idyllic scenes and conversations among shepherds. His influence extended to later poets, including Virgil and Pope, who drew inspiration from his themes and style, solidifying his legacy in the literary world.
