Still Life of Oysters, a Nautilus Cup, a Roemer, Lemon and Other Objects, Willem Claeszoon Heda
On Sotheby’s (zoomable). Direct link to image file here.
I love the subtle sheen of colors in the nautilus cup, and the way the glassware almost disappears into the dark background.
Interesting to compare to this somewhat more elaborate still life by Heda’s contemporary, Pieter Claesz, also featuring a nautilus cup.
