Silver cup from <a href="https://en.wikipedia.org/wiki/Berthouville" class="extiw" title="en:Berthouville">Berthouville</a>'s treasure, Eure département, Normandy. In James Curle, 1917, p. 137, fig. 7. Curle says about it : <br>
« scyphus from the Bernay treasure. The principal figure in the design is a female Centaur seated on the ground. Her right hand is raised, her left holds a mirror. Her head, with floating hair wreathed with ivy, is turned back to the right; behind her is a basket of fruit, and a Cupid grasping the tall flower-stem of a poppy. Beneath the mirror is the cista mystica with the snake, and to the left a mask and an overthrown  krater, on which stands a cupid blowing a double flute, while from the mouth of the overturned vessel springs a panther.  » (Curle, p. 137-138)
