The Count of Lucanor consults his patronio councillor on various matters, in his desire to always work in a sane way. The latter tells him, in each case, a story or apologist, from which it is clear what the count should or should not do. Each of these examples ends in a moral written in verse. So far the structure of the book. But what makes this work a true jewel of Castilian prosa is its style: simple, sober, without the rhetorical ornaments that define the preceding literatures.
