This print, from the first half of the 18th century, was issued in Paris by Jacques Chiquet. Entitled “Miroir de la pécheresse” [Mirror of the sinful], it is now in the collection of the Musée des Civilisations de l’Europe et de la Méditerranée, Marseille .
This allegorical engraving shows in the bottom side a dog-like devil standing against an erect snail. The sinistral shell has axial stripes suggesting ribbing, and relatively few whorls. The animal is stylised with all four tentacles shown, and has an eye-spot.
