This fascinating volume explores an important fifteenth-century illustrated manuscript tradition that provides a revealing glimpse of how western Europeans conceptualized the world.

From the classical encyclopedias of Pliny to famous tales such as The Travels of Marco Polo, historical travel writing has had a lasting impact, despite the fact that it was based on a curious mixture of truth, legend, and outright superstition. One foundational medieval source that expands on the ancient idea of the “wonders of the world” is the fifteenth-century French Book of the Marvels of the World, an illustrated guide to the globe filled with oddities, curiosities, and wonders—tales of fantasy and reality intended for the medieval armchair traveler. The fifty-six locales featured in the manuscript are presented in a manner that suggests authority and objectivity but are rife with stereotypes and mischaracterizations, meant to simultaneously instill a sense of wonder and fear in readers.

In The Book of Marvels, the authors explore the tradition of encyclopedias and travel writing, examining the various sources for geographic knowledge in the Middle Ages. They look closely at the manuscript copies of the French text and its complex images, delving into their origins, style, content, and meaning. Ultimately, this volume seeks to unpack how medieval white Christian Europeans saw their world and how the fear of difference—so pervasive in society today—is part of a long tradition stretching back millennia.

This volume is published to accompany an exhibition on view at the J. Paul Getty Museum at the Getty Center from June 11 to September 1, 2024, and at the Morgan Library & Museum from January 24 to May 25, 2025.

Heroes and Marvels of the Middle Ages is a history like no other: it is a history of the imagination, presented between two celebrated groups of the period. One group consists of heroes: Charlemagne, El Cid, King Arthur, Orlando, Pope Joan, Melusine, Merlin the Wizard, and also the fox and the unicorn. The other is the miraculous, represented here by three forms of power that dominated medieval society: the cathedral, the castle, and the cloister. Roaming between the boundaries of the natural and the supernatural, between earth and the heavens, the medieval universe is illustrated by a shared iconography, covering a vast geographical span. This imaginative history is also a continuing story, which presents the heroes and marvels of the Middle Ages as the times defined them: venerated, then bequeathed to future centuries where they have continued to live and transform through remembrance of the past, adaptation to the present, and openness to the future.

Human twins have many meanings and different histories. They have been seen as gods and monsters, signs of danger, death, and sexual deviance. They are taken as objects of wonder and violent repression, the subjects of scientific experiment. Now millions are born through fertility technologies. Their history is often buried in philosophies and medical theories, religious and scientific practices, and countless stories of devotion and tragedy. In this history of superstitions and marvels, fantasies and experiments, William Viney—himself a twin—shows how the use and abuse of twins has helped to shape the world in which we live. This book has been written not just for twins, but for anyone interested in their historical, global, and political impact.
