“This ewer is an extreme example of the auricular style, an anti-classical form of design with a flaccid, fluid appearance comprising fantastic sea-creatures and human body parts like bones, ears, sinews and folds of skin. The ewer captured the imagination of numerous painters, in part because its bizarre form allowed it to pass as an object from an ancient and foreign land.”
Examples of the numerous paintings in which it is incorporated include a kitchen scene by Adriaen van Nieulandt…
the Isaac Blessing Jacob by Gerbrand van denn Eeckhout…
and a large canvas by Govert Flinck…
Spot the ewer…

how very odd—and faintly creepy. Sort of like dinner ware from “Alien”
