This book takes its title from a poem from the early 13th century and falls into two sections. The first consists of untitled and unnumbered poems like those of "La voz a ti debida"; the second comprises eight long poems with individual titles. The subject-matter and approach is much the same as in the earlier collection but there is more assurance in the handling of the poetry. Again there is an emphasis on the inability of language to convey what the poet feels.
