Dodona is among the best-known Greek oracles, with thousands of lead lamellae relating the questions asked to Zeus. But understanding how they were used, relying on epigraphy, with the literary tradition and its usual stereotypes about oracles, proves impossible. Literary sources emphasise the ambiguity of questions and answers, while the engraved questions, ignored by the literary tradition, are obviously formulated to be answered by ‘yes’ or ‘no’. From this basis, this essay explores when these questions (and the answers that we do not possess) were written and used in some ritual way(s). This could have been at the beginning or the end of the consultation, or somewhere in between. We do not know if the texts transpose the question asked orally verbatim, nor if all the consultants were following a strict procedure. Most of the questions are too short to be understood by the officials, and the consultation was partly if not fully oral. Some detours about quasi-identical questions, abecedaries and lot oracles clarify this picture, but this enquiry highlights our ignorance about the procedure and warns against simplistic interpretations drawn from incomplete documentation.
