The Rijksmuseum in Amsterdam has an extensive collection of engravings, one of which is this one designed by Jacobus Kempener, entitled “Grotesque vase with flowers, including a sunflower” . This engraver worked in Cologne, Germany, around 1650 . Although this engraving has not been dated, it is probably from the mid-16th century (Sadeler, the publisher, died in 1665).
The interesting thing about this engraving is: it might have served as inspiration for the painted flower still-lives, which were later made manyfold, mainly in Flanders and Holland. For the first time we find here the association between a vase of flowers and snails. The two snails are mirrored, one dextral and one sinistral. Both are stylised, seemingly ribbed, and have two tentacles.
