Entre la nature et le rite: Réflexions sur le statut des signes-voix divinatoires

In ancient Greece, among the signs stemming from the natural world were a series of sounds that, strictly speaking, were opposed to the technical or artificial divination and are connected to the sphere of that which is formless, indefinite, and unruled. How did these signs suggest a relationship with a rule that might reveal the code governing this form of prediction? Is it possible to identify the formal structures of such a code? The distinctive features and variety of these sound signs, generally considered as the expression of a knowledge based on arbitrariness, chance and ad hoc interpretation, lead one to take into account some aspects of the science of signs in the Antiquity that differ from Aristotle's tradition and question the definition of divinatory signs.
