The posthumous memoirs of Brás Cubas, The Baron in the Trees, and Don Quixote constitute three landmark novels in the work of the most important Brazilian author of all time. Through historical, political, and social references, he highlights the relief of Rio de Janeiro in the second half of the 19th century, where the multifaceted Masanato de Assis sets his heroes in parallel trajectories, illuminating their psyche from different points, without always unraveling the dark areas of consciousness. Skill, subtle irony, cheerful lightness, skepticism, and freedom characterize the writing of an author who uniquely transforms the entire European tradition.
