Upon reading Adam Buenosayres, by Leopoldo Marechal, various metapoetic reflections can be found on the essence of poetry, inspiration, the mode of literary representation. However, some sections provide a greater condensation of these reflections. A hermeneutical analysis is presented of two sections of this book in which Marechal’s poetry is explained with clarity, order and condensation: the «Prólogo indispensable» and the episode of Ciro Bower (chapter I, book IV). In addition, the «Claves del Adán Buenosayres» are reviewed. This analysis is completed with comments about Marechal’s poetry taken from specialized literature.
