A Misleading Source: The Fortuna of a Sixteenth-Century Engraving and Its Impact on The History of Roman Baths Studies

In this article, I follow the mixed fortunes of a woodcut depicting a cutaway view of a set of ancient baths, so far neglected by modern scholarship. First published in a mid-sixteenth-century treatise on balneology and based on a misinterpretation of Vitruvius (5.10.1), it reappeared as a copy of a Roman wall-painting in several eighteenth-century antiquarian works. The remarkable resonance enjoyed by this image in specialist and popular publications until the early twentieth century makes it one of the most influential and controversial sources in the history of Roman baths studies. In exploring the reasons behind the enduring, uncritical acceptance of this depiction, I raise broader questions concerning the nature and extent of intellectual networks in eighteenth-century Europe.
