The history of oral narratives is in the grip of a paradox. The voice of their past telling is no longer evident, and what is evident is no longer oral. Once committed to writing, oral tales become literature, bearing the consequences of this transformation that occurs under specific social, religious, economic, even technical, circumstances.1 The shift from orality to literacy involves thematic, stylistic, and poetic modifications, and although in their new state the tales have a relatively higher degree of stability, they still can offer us glimpses into their performance history.
