The Cleveland Museum of Art's medieval collection is internationally renowned for the importance and quality of its holdings, and consists of works produced in the Early Christian, Byzantine, Carolingian, and other periods. The medieval collection exists largely as a group of masterpieces rather than a comprehensive or encyclopedic survey of the history of medieval European culture. This unique collection includes many objects that are not replicated elsewhere in the United States, including the Early Christian sculptures known as the Jonah Marbles.
