Eduardo Afonso Viana (Lisbon, 28 November 1881- Lisbon, 21 February 1967) was a Portuguese painter. He was one of the members of the first modern generation in Portuguese painting, like Amadeo de Souza Cardoso and Almada Negreiros. He was more conservative in his approach to modern painting. The best examples of his assimilation of the modern styles in his work appears in the paintings he did in 1916, due to the influence of both Robert Delaunay and Sonia Delaunay, who he befriended during their presence in Portugal. He latter followed the post-impressionist style inspired by Cézanne in some of his best paintings. He's represented in some of the best Portuguese museums, like Chiado Museum, in Lisbon, and the National Museum Soares dos Reis, in Porto.
Viana's painting were a mirror of the life of his country. One of the best examples of this motif is his 1916 painting 'In Revolt', in which he showed Portuguese life through colorful arcs. But Viana was fond of Nature. He had a strong attachment to naturalism. In 1917, he painting 'K4: The Blue Square', considered a homage to Portuguese modernism, was inspired by the book of the same name by Almada Negreiros and was dedicated to Amadeo.
