Focusing on a critical investigation of a Carlos Drummond de Andrade s work – the book Uma pedra no meio do caminho: biografia de um poema – the dissertation A brief metacritical experiment: the poem of the stone by Carlos Drummond de Andrade offers an innovating discussion about the configuration, the authorship and possible limits of historiographical writing. The mentioned book can be read as an unique self-attribution of a place in Brazilian literature history by the poet himself, who vigorously participating of the intellectual and artistic life of his time, took care of his own archive by registering the reception of his poetic work. The book, published in 1967, assembles diverse critical material about the repercussion of the poem No meio do caminho (1928) which provoked a range of positive and negative reactions from enthusiastic acceptance to violent rejection due to its aesthetical innovative formal feature. Anchored on theoretical repertoire of the Reception Aesthetics and of the historiography alternative proposals, this dissertation discusses the possibility of understanding the drummondian work as experiment of a history of literature in expansion, which goes beyond the borders of biography, autobiography and historiographical writing.
