This seat, inspired by those of the officers of the initiatory association, very well preserved, is decorated with a characteristic head tapering towards the chin, with a crenellated beard and a masked naso-frontal ridge.

In the westernmost part of the Bembe country, there are, historically related or not, several subgroups of ethnic groups, called Bembe, Boyo (or Buyu), Basikasingo (sing. Sikasingo), etc.

In this region of ancient cultural contact, historically and culturally distinct groups have influenced each other in different ways; the process of acculturation and integration was disrupted by the regroupings that took place during the first sixty years of our century.

Among the Western Bembe, the Bwami society (based on the Lega model but less complex) uses wood, bone and ivory figurines for its initiations into the highest grades.
