Narmer Palette
The image is featured specifically on decorated cosmetic palettes from the Predynastic period of Egypt, and more extensively, as design motifs on cylinder seals in the Protoliterate period of Mesopotamia (circa 3500–3000 BC). Examples include the Narmer Palette and the Small Palette of Nekhen (Hierakonopolis). The cylinder seal of Uruk (image above) displays the motif very clearly. Typically, two creatures are depicted, with their necks intertwined.
