Lais are short narrative poems that originated in the medieval period, particularly associated with the Breton culture. They often tell stories of love, adventure, and chivalry, typically featuring themes of courtly love and moral lessons. The most famous collection of lais is attributed to the 12th-century poet Marie de France, who wrote several lais that have survived to this day. These poems are characterized by their lyrical quality and use of rhyme, making them accessible and engaging. Lais were often performed orally, allowing them to reach a wide audience. They played a significant role in the development of French literature and influenced later poetic forms.
