Joan Brossa was a Catalan poet, playwright, graphic designer and visual artist. He wrote only in the Catalan language. He was one of the founders of both the group and the publication known as Dau-al-Set and one of the leading early proponents of visual poetry in Catalan literature. Although he was in the vanguard of the post-war poets, he also wrote hundreds of formally perfect sonnets, sapphic odes, and sestinas as well as thousands of free and direct poems.
