Thomas Heatherley made this “Fairy resting on a mushroom” . As far as I could trace this is now in an unknown (private?) collection; this oil paint on canvas was made ca. 1860 . The artist acted as principal of an art school in London, now named after him .
Several snails may be seen in this painting, only one has an animal (albeit without a tail). Interesting is the scene in the left-hand corner, where a (somewhat stylised) snail is pointing its two larger tentacles forward to oppose three men with different weaponry. It is a very nice reference to the ‘knight v. snail’ theme in medieval manuscripts. As far as I know, made before this theme surfaced in art historian literature. Also notice the angel-like figure standing on top of the shell; it reminds me of the Statue of Liberty in New York.
