“Suche nach der Treue. Einhornjagd” [Search for the Truth. Hunting the Unicorn] is the title given to this wall tapistry, which originated 1500–1510 in Strassbourg and is now in the Schweizerisches Nationalmuseum, Zurich .
In the right-hand part two snails are seen, which are both stylised. The reddish one may have been modeled after Arion cf. rufus (L., 1758), the greyish one is a sinistral (imaginary) species. A similar specimen may be seen in the central part, near the water.
