Béroul was a medieval poet from the 12th century, known for his work on the legend of Tristan and Isolde. He is believed to have originated from the region of Normandy, France. His most famous contribution is the narrative poem "The Romance of Tristan," which explores themes of love, betrayal, and chivalry. His version of the Tristan story is one of the earliest and most influential, shaping later adaptations in literature and art. Béroul's work emphasizes the emotional and tragic aspects of the love story, setting the stage for future interpretations by other writers, including Thomas of Britain and Wagner.
