摘要：This article offers a typology of the five different kinds of lacunae present in Manuscript 6376 at the Biblioteca Nacional de España in Madrid, which contains most of the works of Juan Manuel. This article identifies the kinds of lacunae affecting the Libro de las tres razones and suggests that some of those blank spaces were meant to be devoted to illuminations that were never executed. This article also suggests that the Libro de las tres razones, as it stands before us now, is an incomplete copy of a lost historiated exemplar in which the author developed a visual support to accompany the political message of his works.
