AbstractThis article characterises Quevedo's “musa décima”, his poetry not included in the posthumous editions, in order to deepen its features and to consider the future critical edition of the whole. The limits of the corpus are still blurred, due to the abundance of poems of doubtful attribution. After a brief contextualisation in the complex transmission of Golden Age poetry, the catalogue of poems, their textual sources and outstanding literary features are dealt with: jocular matter and antigongorism, burlesque sylvas and poems of praise, which situate the author at the beginning of his career. Unveiling this “peripheral” corpus will have an impact on the “nuclear” poetry of Quevedo.
