The present investigation develops the lines in which is presented the relationship between technics and art on Heidegger’s writings of 1935-1938, emphasizing in his text Introduction to metaphysics, widening then the research to other Kehre texts that shows their relation with language, Ereignis and the Gestell. It will be fundamental for our purposes the notion of Deinón that Heidegger takes from Sophocles and that applies to the polemic relation that appears in technics and the essence of arts, which will also be the ground for his thoughts about Machenschaft and the actual donation of Being as Gestell.
