This drawing is one in a series illustrating flowers (mainly tulips) and an occasional animal. These drawings were made by Nicolas Robert (1614–1685) and are now in the collection of the Fitzwilliam Museum, Cambridge. One the drawings here shown has two tulips (“Apricot pennaché” and “Grinaq”), two butterflies, a beetle and a snail .
The (slightly stylised) snail is a dextral specimen, the shell has 3.5, regularly increasing whorls and the animal has all four tentacles shown. The colour pattern suggests that it could be, e.g., Arianta arbustorum (Linnaeus, 1758), but it is possible that another Helicidae species has served as model.
