Philadelpho Menezes (1960–2000) was a poet, essayist, translator, theoretician and professor. He was in the vanguard of the experimental poetry movement that developed throughout Brazil starting in the 1950s. He grouped poets and innovative genres of poetry into exhibitions such as Poesia Intersignos (Centro Cultural São Paulo, 1985). Another exhibition he organized for CCSP was the 1ª Mostra Internacional de Poesia Visual of São Paulo (1988), with the participation of more than 300 poets from almost 40 countries. In 1997, he organized the special room “Poesía Sonora” as a part of the event Arte Tecnologia (Itaú Cultural, São Paulo), and in 1998, he was a curator of the event Intersignos, do impresso ao sonoro e ao digital (Paço das Artes, São Paulo). In his own poetry, he made use of nonverbal elements to structure what he coined as “intersign poetry.” He earned his master’s degree and his PhD at Pontifícia Universidade Católica de São Paulo (PUC/SP), with postdoctoral research at the University of Bologna (Italy). As an instructor, he taught courses at the postgraduate level in communications and semiotics at the PUC/SP. Among the several books he published in his specialty are Poética e Visualidade - Uma Trajetória da Poesia Brasileira Contemporânea (Campinas: Editora da UNICamp, 1991).
Regarding the Brazilian experimental poetry movement of the 1980s—period when Menezes began to publish his work—there is an essay by the Spanish artist/designer based in Brazil, Julio Plaza, who curated the 17th International Biennial of São Paulo (1983), written under the title “Arte e videotexto”.
