Most African sculpture was historically in wood and other organic materials that have not survived from earlier than at most a few centuries ago; older pottery figures are found from a number of areas. Masks are important elements in the art of many peoples, along with human figures, often highly stylized. There is a vast variety of styles, often varying within the same context of origin depending on the use of the object, but wide regional trends are apparent; sculpture is most common among "groups of settled cultivators in the areas drained by the Niger and Congo rivers" in West Africa.[1] Direct images of African deities are relatively infrequent, but masks in particular are or were often made for traditional African religious ceremonies; today many are made for tourists as "airport art".[2] African masks were an influence on European Modernist art, which was inspired by their lack of concern for naturalistic depiction.
