Lea Lublin (Buenos Aires, 1929), a resident of Paris since the 1960s, was a distinguished, innovative conceptual artist in Argentina, above all, for taking advantage of technology in art. The text of this document corresponds to her work Fluvio Subtunal [Subtunal Fluvium], created for the inauguration of the subfluvial tunnel, which linked the cities of Santa Fe and Paraná, capital of the Entre Ríos Province, under the Paraná River. It was the most important work of engineering in Argentina at the time. Lublin’s environment was produced with the sponsorship of the Instituto Torcuato Di Tella and the Asociación de Lucha contra la Parálisis Infantil [Victims of Infantile Paralysis Association]. In fact, several environments were looking to stimulate the observer around the same time, such as La menesunda [The Hodgepodge] (Marta Minujin and Rubén Santantonín, 1965), Importación-exportación [Import-Export] (Marta Minujín, 1968), Barbazul [Bluebeard] (Luis Fernando Benedit and Vicente Lucas Marotta, 1966), and Terranautas [Terranauts] by Lublin herself. Document compiled in the catalogue for the 1970 exhibition at Galería Carmen Waugh where she exhibited the photographs of her works, which were projected on movable screens, realized by Humberto Rivas, Pedro Roth, Fermín Cardona, Robert Phillips, and César Caldarella.
