Oculate Being Mask, 300 BC-AD 1. This rare mask incarnates a supernatural being who may have been the patron of an early fertility cult on Peru?s south coast. Its traits insinuate power, especially the stuck-out tongue and the serpents that slither over the face to form a halo-like corona. Unexplained are the shape of the nose and the small figure wearing a similar mask. The mask could have served as the face of a mummy bundle or an object; the projecting eyes might rule out use by a living performer.
