With the reconstruction of Heidegger's Nietzsche-experience the essay shows a conceptual place of late modernity, intended as the age of nihilism. Through a close comparison with the social, religious, political, philosophical and literary contest, in which it grew up between 1910 and 1946 the Heidegger's interpretation of Nietzschean philosophy, the study follows two paths of research, constantly crossing from an analytical point of view and under a methodological perspective. From one hand, in what sense the figure of Nietzsche in Europe, but especially in Germany, has worked in the first half of the twentieth century as a sort of political and philosophical device on the issue of nihilism. On the other hand, by a careful analysis of Heidegger's writings it's possible to identify the ambiguous traces of Nietzsche in the development of philosophical thought of Heidegger.
Compared to that the presence of a worm, we can see the political and philosophical corrections that Heidegger used in order to put a remedy to the corrosive force of Nietzsche-experience.
