The description of this satirical print in the British Library reads “Satires on clerics and aristocrats; two images of circular format on single plate, one with an ecclesiastic with a protruding nose, holding a censer, the other with a large snail climbing a dying tree”. It was made by an anonymous artist in 1790 .
The large snail on the picture at right appears to be accompanied by a second, similar specimen in the background. Both are sinistral, with all four tentacles shown, the shell with marked growth striae and an extremely large aperture. Despite the realistic appearance this is likely an imaginary species.
