Punning and Metamorphosis in Celtic Design

The image below is an example of shape shifting in the form of a reversible face. Discovered in a woman's tomb at Bad Durkheim in the Hunsruck-Eifel, Germany, this example was found on a sheet-gold ornament dating to the late 5th century or early 4th century B.C.

Bearded man's face

Rotated one way, it shows an older, bearded, man's face.

Clean-shaven head with crown

Rotated the other way, it shows a clean-shaven head with a leaf-crown.

Reversible face, Late 5th to early 4th century BC. Gold, 2/3" high.
