Other versions of this plaquette exist in the Bode Museum, Berlin (a rectangular work), the Victoria and Albert Museum, London, and the Louvre, Paris.1 Some bear the monogram IO(hannus) B(ernardi) F(ecit). The composition may have derived from an engraved crystal plaquette that Giovanni Bernardi made for Cardinal Alessandro Farnese II.2 This aftercast from the sixteenth or seventeenth century has some loss of detail.
