"Grebo" means "leaping monkey people," a reference to their flight from a former homeland near the Sahara. The ruler known as bodio lives in near total isolation and functions as grand priest. The Grebo sculpt several types of masks which incarnate the spirits of the invisible world who live in the forest. Masks similar to this one may be related to the war masks, more abstract and with elongated nose and one or more pairs of tubular eyes.
