The novel is a playful and complex narrative that intertwines the stories of two characters living centuries apart: the medieval Duke of Auge as he goes on various adventures, and a modern-day Frenchman named Cidrolin who spends his days idly lounging on a barge moored on the Seine. The narrative switches back and forth between the two timelines with each chapter, employing a variety of literary styles and linguistic puns. The book is known for its experimental use of language, its humorous take on historical and contemporary life, and its exploration of themes such as time, identity, and the cyclical nature of existence.
