This publication brings together, for the first time on the subject, a collection of works that address various issues relating to the use of models in artistic creation in the Gothic era. The methods of circulating artistic forms in the West between the twelfth and fifteenth centuries are examined from four different angles: the model, model books, three-dimensional models that challenge the notion of artistic versatility, and the technical processes of transfers, particularly in the art of stained glass and goldsmithery. Drawing upon very concrete case studies, the authors base their work on specific, wide-ranging examples covering a variety of artistic fields, and in so doing, provide readers with valuable insight into these practices, which, although often presumed, still remain relatively difficult to understand within the context of medieval artistic production.
