Lea Lublin (Buenos Aires, 1929), a Paris resident 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 [Sub-Tunnel Flow], 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 setting was produced with the sponsorship of Instituto Torcuato Di Tella and the Asociación de Lucha contra la Parálisis Infantil [Victims of Infantile Paralysis Association]. In fact, several installations were aiming 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.
