In the late summer of 2013, within the framework of the retrospective “Hélio Oiticica: The Great Labyrinth”, the MMK Museum für Moderne Kunst Frankfurt am Main presented three outdoor installations by the Brazilian artist in Frankfurt’s Palmengarten. One of these works was the Penetrável PN 14, a walk-in room installation that Oiticica designed in 1979 during his time in New York. Its realization in the botanical garden provided an occasion to explore the specific format of the Penetrável developed by the artist, and to investigate its specific curatorial conditions, potentials and challenges. Discussions on these matters were carried out with artists, curators and critics. The Penetráveis, pavilions and platforms as temporary exhibition formats were a further topic of concern. All the many conversations conducted over the course of the project yielded the essays now filling this book. Part 2 of the publication documents the artistic contributions created especially for the Penetrável PN 14 in Frankfurt and the films selected for the accompanying film programme. The MMK Museum für Moderne Kunst Frankfurt am Main, one of the curatorial studies programme’s cooperation partners, assigned the task of developing an overall curatorial concept for artistic interventions to be carried out in and around the installation. The programme took place over a period of two months in the Palmengarten. Twelve artists, including a number of artists’ collectives, were invited to develop site-specific works and respond to the Penetrável PN 14, but also to the Palmengarten as a unique venue of artificial exoticism. A range of widely differing propositions was the result: experiments with sound, language and dance, projections, evening salons and encounters as well as a specially conceived evening film programme.
