Abstract: Our title comes from a note left by Angelo Colocci in the opening leaf of the Cancioneiro da Vaticana, Vat. Lat. 4803 (V). Despite the consensus on the fact that this note aims to draw attention to V’s acephaly, with regard to its “twin” B (Cancioneiro da Biblioteca Nacional de Portugal, cod. 10991), it raises questions that mostly remain unanswered. Our reflections concern the material structure of the two codices and the possible characteristics of the exemplar.
