Cocoliche, that curious dramatic character improvised under the circus tent during the last decades of the nineteenth century, is no longer a vital aspect of Argentine life today. Yet his caricatured presence over a period of fifty years proved critical in the creolization of Italians and natives as well as in the sociocultural redefinition of Argentina's “national character.” Creolization (the cultural redefinition negotiated by two or more diverse groups coming into contact—in this case, Italians and Argentines) yields a new ethic and aesthetic order wherein the presence of each group becomes integral to the national whole. As will be shown, Cocoliche became a key vehicle for this process of creolization.
