One of the major problems (or sometimes pseudo-problems) that archaeologists and historians encounter in the study of ancient cultures is the need to differentiate and to identify the sources of the various concepts, techniques, institutions, forms, designs, motifs, etc., that, at any given moment of time, form the constituent elements of the culture or cultural product to which they have turned their attention; or—to pose the question in its proper framework—to analyse the process of cultural formation inherent in the subject (...) of their study. Such considerations have a special significance for archaeologists, whose essential concern is with the often incomplete assemblages of material remains left behind by the cultures and civilizations of the past, and whose central task is to enumerate and reconstitute the structures and processes that were operative in the societies in question. The study of acculturation—culture change, cultural diffusion, “stimulus diffusion,” culture contact, etc.—has been part of the theoretical and empirical concerns of anthropologists and sociologists since some decades ago, and the subject of an old and now almost abandoned debate. While the terminology of the social sciences concerned with living societies can also be found in archaeological and historical discussion, such concerns have had inadequate application in the fields of archaeological and historical practice. What has dominated and, to a great extent, continues to dominate historical studies is what we might call “the ‘theory’ of influence” and its corollary, “the migration hypothesis.” Thus, it would not be an exaggeration to say that one of the leading aspects of the study of a past society or culture is the concern with the “parent” culture(s) which influenced it, or the search for the location of its “migratory origins.” While this is especially true of studies relating to the societies of the Third World, it is not exclusively so—as we see, for instance, in the case of European prehistory. The immediate epistemological sources of such approaches are not difficult to identify, being principally located in 19th century diffusionism and, as we shall see shortly, in colonial ideology.
