From dragons, unicorns, and other fabled beasts to inventive hybrid creations, artists in the Middle Ages filled the world around them with marvels of imagination. Their creations reflected a society and culture at once captivated and repelled by the idea of the monstrous. Drawing on the Morgan Library & Museum’s superb medieval collection as well as loans from New York’s Metropolitan Museum of Art and Boston’s Museum of Fine Arts, Medieval Monsters: Terrors, Aliens, Wonders—on view beginning June 8—examines the complex social role of monsters in medieval Europe. It brings together approximately seventy works spanning the ninth to sixteenth centuries, and ranging from illuminated manuscripts and tapestry to metalwork and ivory.  The show explores three key themes: “Terrors” demonstrates how monsters enhanced the aura of those in power, whether rulers, knights, or saints. “Aliens” reveals how marginalized groups in European societies—such as Jews, Muslims, women, the poor, and the disabled—were further alienated by being depicted as monstrous. The final section on “wonders” considers the strange beauties and frightful anomalies such as dragons, unicorns, or giants that populated the medieval world.
