"Poesías completas" by Antonio Machado is a collection of poetry published across four successive editions between 1917 and 1936. Each edition expanded upon the last, gathering Machado's poetic work from 1899 onward. The final 1936 edition was the last prepared and revised by the poet himself. The collection includes poems attributed to his apocryphal creations Abel Martín and Juan de Mairena, offering a comprehensive view of Machado's evolving poetic voice across nearly four decades of literary production.
