Scanning the corpus and repertoire of anthropological science, insofar as we wish and are able to, we note that ethnological observations and studies on theatre are not lacking, but that they seem to have been isolated opportunities for investigation that have never grown into a research tradition.

Even before Erving Goffman, in his studies of interaction, develops and makes the most of the metaphor of a daily life entirely composed of representation, or even stage acting, sociology had already stolen from theatre a number of terms and modes particular to it: the concept of “role”, to take the most classic example, but also the term “actor”, which sociology in fact translates as social actor.
