This discussion of some data from Southern Quechua and Southern Aymara spoken texts recorded during classic divinatory sessions, reveals how this kind of ritual speech, based on fixed sequences, contains variable elements too, being the relationship between a specific “situational context” and the divinatory speech event. Especially, the analysis concentrates on a specific type of speech acts, employed to point out the source of information in the Quechua and Aymara language families. The same devices are employed with a specific performative function in the context of divination: To “officialise” the message of the oracle and to contrast this to the speech acts of the seer.
