SUMMARY The present investigation frames the conceptual art that includes the body as an artistic supponrt in the intervention of nature: body-nature-work, within the cultural context of the Spain of the decade of years 70. Concretely through the performances and of the interventions as sculptures or installations. Two are the artists subject that occupies to us: Ŕngels Ribé, who in the 69 makes works with characteristics that located her in European land art, and Fine Miralles, who is the pioneer of the Cos - Natura or Body- Nature- Works and that because of the chronology of these works they are contemporaries of Ana Mendieta, who is adjudge as being the pioneer. Our central objective will be to emphasize the omission that the art history talking about the European land art and specifically Spanish, has done in relation to two Catalans land artists, searching that they could be include in allusive text editions or does that from this date are generated in the subject of land art and in Catalans’ performances and Spanish too. Also, we referred works of different body treatments and deepened in the accomplishments of Gina Pane, Ana Mendieta and Valič Export, being creatives that agree with the visions and expositions from Ŕngels Ribé and Fina Miralles. In the same way, we will treat the characteristics that define The European land art, we will emphasize those that differentiate it from the American, and that places them within that sort of the art, referring in specific works of Andy Goldsworthy, Richard Long, Giuseppe Penone and in resistance by some of its appreciations to the American Robert Smithson. And of all of them, and others like: Vanessa Mexican Beecroft and of the Carmen Neuhauss Arvizu, Yolanda Gutiérrez, Omar González and Reto Morger, that also count on thematic, formal points of contact or of proposal in their works with the ones of Fina Miralles and Ŕngels Ribé. We will analyze the most representative works of Ŕngels Ribé and Fine Miralles of the decade of the 70’s, in which specially they worked conceptual art in different supports and special Cos- Natura: Body-nature-work. And that will confirm their notoriety and how they were anticipated for this period of time.
