Drooping, heavy eyelids, glaring teeth, horns, a suspicious, crusty surface, or generally crooked demeanor are features that proclaim these masks to be ugly, aggressive spirits to be feared and certainly not emulated. Their black color connects them visually to both the realm of the ancestors and to the darkness that cloaks the unknown. The mask at right with horns and encrusted surface is made of a hard wood that is now extinct; this, combined with its signs of use, suggests it is the oldest of the three. The other two masks with their twisted faces represent ugliness and served as warnings: Behave! Or you, too, might come to look like this! In addition, the mask at center appears to have the head of an owl integrated into its superstructure, a reference to a soul that is emotional and instinctive, lacking the preferred human traits of culture and restraint.
