“Venus and Cupid on a snail” is the title of this drawing after Hans Brosamer. This copy in pen and bown ink and gray brown wash over preliminary drawn in black chalk or charcoal, is now in the collection of the Metropolitan Museum of Art in New York. It is dated 1538 .
The snail has at least 4 whorls (the top is obscured by the Venus figure), a somewhat thickened lip, and a smooth, sinistral shell. The animal is stylised, with a protruding head and two tentacles only. The tail has been omitted.
