[EN] In the poetics of Le Corbusier, art appears as a continuous and articulate presence, as proposed in the dialogs between painting, sculpture and architecture, a process that converges, later, in the notion of the synthesis of the arts. It is on this aspect of his work that we focus exploring texts written by the architect on the theme. The proposed collaboration between the major arts—architecture, painting and sculpting—is recorded in a paper that the architect presented during his second visit to Brazil, in 1936, when he met Lúcio Costa, the Brazilian architect and theoretician, who was attuned to the poetics of Le Corbusier concerning the relationship between architecture and visual arts. The paper by Le Corbusier A Arquitetura e as Belas Artes [Architecture and Fine Arts], from 1936, emphasizes the idea of modern architecture in dialogue with the machine age, and to this well-known formula, a new topic is added: the collaboration between architecture and the major arts of painting and sculpting. In this way, Le Corbusier in 1952, participates in the International Conference of Artists, organized by Unesco in Venice, this conference was another opportunity for dialog between Lúcio Costa and Le Corbusier, emphasizing the poetic dimension of the architecture.
