Stone figures for the protection of crops The best known African figures carved in stone come from the regions inhabited by the Kissi, the Mende and the Sherbro. These are small squatting figures believed to be very old. They are often known also as nomoli or pomta and are nearly always uncovered in tilled land. In many cases residues of earth and roots can still be found, others were kept on domestic altars and their patina is formed as a result of the attentions of their owners.

The dried roots often found attached to the ceramic surface are, instead, a sure indication of authenticity. The find was made in dry tin mine galleries, for which reason they generally showed few signs of contact with the earth. The ascertainment of their authenticity is therefore not based on scientific tests so much as on a long and intense experience in examining figures of this kind.
A significant example of this is comparing the enlarged images of the surface of the head of an authentic figure with those of a fake: Bronze sculpture in TbilisiGeorgia.
