In the Musée des Beaux-Arts in Rennes, France, a series engravings is conserved, made by Adriaen Collaert (c. 1560-1618). This Flemish designer and engraver has made this series of 10 prints (“Paysages”) with religious scenes. Two of these have malacological figures.
The first is a print “Le Baptême du Christ”, where in the ornamented border two snails are seen. They have both shells with few whorls, the last one with axial stripes (which could be interpreted either as sculptural elements or as part of the colour pattern); a spiral band seems also present along the periphery of the shell. The animal is somewhat stylised, with two tentacles only.
In the second print the snails are in the lower border. The same species seems to have served as model, here with more spiral elements being present.
In both prints a dextral and sinistral specimen is present, positioned in such a way that it seems purely for reasons of symmetry.
