Nautilus ewer with openwork and engraved pewter mount. Portugal, 16th/17th century H. 16.5 cm (corrosion, some missing parts and restorations) This curious ewer is a real object of curiosity, as these mounted shell pieces were usually mounted in copper or gilded silver. However, the Musée du Louvre holds a pilgrim's gourd in opaque light-blue glass with a pewter mount that belonged to the Sauvageot collection (inv. OA 457). The corrosion of the pewter seems to indicate a long stay in an aquatic environment.
