A Japanese sword guard is in the collection of the Musée des Beaux-Arts, Nancy. Decorated with some snails, this 18th century object has been made by an anonymous artist of bronze inlaid with gold .
On the recto side, two snails are seen. They have both sinistral shells, and show signs of axial sculpture or ribs; the animals have both all tentacles, of which three are shown. As yet an unidentifiable species.
On the verso side a structure is seen that could be interpreted as a shell seen from below: the central hole being the umbilicus, the aperture seen in the right upper part; here too the last whorl shows some axial ribs near the aperture (seen in the right lower part of the structure).
 MBN, inv. AD.796. Joconde | escargot (réponse #135).
