A production as precious as the transparent glasses that made the reputation of Venice and the island of Murano, the enamelled and gilded glasses of the Renaissance were particularly prized from the end of the 15th century. So much so that, at the beginning of the 16th century, glass workshops all over Europe set about developing their own production, particularly in France. Combining the contributions of the history of art, archeology and scientific analyses, the exhibition will thus attempt to clarify the attributions (Venice? Way of Venice?) and the dating (between the 15th and 19th centuries) of these works that we thought we knew so well.
