The mask hides as much as it reveals, “denies as much as it affirms”, as Claude Lévi-Strauss asserted. Very often the holder of a secret, the mask conceals that which only the initiated should know. The mask’s power also lies in its capacity to incarnate spirits, a link between man and his ancestors, between the visible and the invisible world.  It is inseparable from a mythical context which structures the mode of existence and thought of the majority of traditional societies. Central to the life of a group or a community, the mask, an indispensable intercessor, is always active. This particular mask is the Bas Sepik from the Melanesie region and scanned for us by a volunteer using roughly 50 photographs.
