The Grebo arrived from the southern Sahara around 1550 and settled on the cost of Liberia, west of the Cavally River. Divided into clans, the Grebo would choose a chief (bodio) who also assumed the function of grand priest. Once named, the bodio would live away from the village in a hut and devote his time to meditation. Needless to say this institution finally fell away as there were not too many people wishing to take on this responsibility with its inherent isolation. The Grebo sculpt masks that incarnate the spirits of the invisible world who live in the forest. These masks appeared during rituals reserved for initiates and at the time of celebrations when the whole clan was able to see them. This abstract mask is formed by a board and decorated with tubular eyes.
