Delivery service: Colissimo Recommended Oak barrel lock carved with two symmetrically opposed dolphins by the central brass screw. This lock, also known as a barrel bolt, is a production whose geographical origin extends from Alsace to the Palatinate in Germany. Period: End of the 18th century/beginning of the 19th century. The locks that block the cleaning doors of barrels were often carved either by the coopers themselves or by professional sculptors who also made window frames or house decorations. The decorations most often depict marine beings, fish, dolphins, mermaids... in connection with the mythology of the wine gods Bacchus and Dionysus.
