Summary and Keywords

Technical processes—or chaînes opératoires—are heterogeneous cultural aggregates articulating raw materials, tools, knowledge, representations, and agents. The nature and arrangement of these elements stem from a web of social, historical, and ecological relations that not only delineate a sociohistorical framework within which artisans operate, but also determine how individuals shape and give meaning to their daily engagement in the craft. Pottery chaînes opératoires have been the focus of a large body of ethnographical studies in Africa since the beginning of the 20th century, most of them developing within the subfield of ethnoarchaeology. Yet pottery chaînes opératoires may also provide crucial information to historians when analyzed through an approach inspired from historical linguistics and tentatively called “comparative technology.” Pioneered by Haudricourt, this approach combines two levels of comparison. The first consists in a minute comparison of different chaînes opératoires within a given field of activity and geographical area in order to identify similarities and differences in tools, materials, gestures, and the organization of operations. This allows for the identification of specific “technical traditions”; that is, shared ways of doing that stem from a shared set of knowledge. The second level of comparison implies a mapping of the technical traditions (be it whole chaînes opératoires or particular stages or components), with the aim of identifying and characterizing their respective spatial distributions: for example, the effects of aggregation or disintegration, possible boundaries, or interpenetrations.

The relevance of spatial distributions in history-oriented analyses of technical processes is twofold. First, spatial distributions compel us to explore the sociohistorical processes from which they resulted; that is, the set of relations—social, economic, political, and ecological—that determine how artisans interact with each other, share knowledge, use tools and materials, cope with changing situations, or seize new opportunities. Second, spatial distributions may reveal strong and time-enduring connections with various kinds of social identities (e.g., languages, political factionalism, regional affiliation, gender, and ethnicity). When the underlying mechanisms of such connections are appropriately understood, they may be used to formulate hypotheses about past processes, including population movements, the development and evolution of political boundaries, identity negotiations, or socio-economical transformations. Here, chaînes opératoires may prove especially reliable for historians since they are less easily and deliberately manipulated than written or oral documents
