The time and space setting of an artifact, feature, or culture. The context of a find is its position on a site, its relationship through association with other artifacts, and its chronological position as revealed through stratigraphy. Certain features or artifacts may be normally associated with particular contexts, for example a pottery type may be found in the context of certain burials. If such an artifact is found out of context, it may suggest the previous presence of a burial, the robbery of a burial, or a place of manufacture of the pots that accompanied burials. An artifact's context usually consists of its immediate matrix (the material surrounding it e.g. gravel, clay, or sand), its provenience (horizontal and vertical position within the matrix), and its association with other artifacts (occurrence together with other archeological remains, usually in the same matrix). The assessment of context includes study of what has happened to the find since it was buried in the ground.
