Poetry... Prose... Art: three definitions for the same work. This is a first edition of this book by Almada Negreiros, one of the most prominent representatives of Modernism and Futurism in Portugal. The green paperback binding is one of the iconic elements of this work and profusely covered in black writing as if a synopsis: "A Invenção do Dia Claro. Written in a manner appealing to all kinds of pride, followed by démarches for Invention and accompanied by the most intimate and general confidences. - Essays for the initiation of Portuguese in the revelation of painting - With a portrait of the author by himself". "Without a master", and "without disciples", as José-Augusto França would characterise him, Almada Negreiros stood out in painting and writing and made important contributions to the magazines Orpheu and Presença. In A Invenção do Dia Claro, the artist contests and intervenes to bring out the lyricism in his literary production.
