L’anello che manca. E quello che non torna in Nathans Tod di Georg Tabori propose a modern rereading of Lessing’s play Nathan the Wise (Nathan der Weise): Georg Tabori’s Nathans Death (Nathans Tod). The paper aims for a comparative analysis of the famous ring parable. Asked by the Sultan to decide which of the three religions owns the truth, Nathan narrates the fable of a magic ring that has been passed from generation to generation and finally lost, when a father with three sons makes two copies of the original one. The ring symbolises the tyranny of a unique truth that has to be overcome, in order to achieve tolerance. My interest focuses on two moments of Tabori’s rewriting of this fable. On the one hand, I analyse the way in which Tabori glosses over the ring parable in the dialogue between Nathan and Saladin thanks to Horkheimer’s and Adorno’s Dialectic of Enlightement (Dialektik der Aufklärung) and to Arendt’s Man in Dark Times (Von der Menschlichkeit in finsteren Zeiten). In the economic and social paradigm of the modern Totalitarianism there is no more place for tolerance. On the other hand, I reflect on the new context in which Tabori places the ring fable narrated by Nathan just before his death in front of the bodies of his dead sons. I consider that choice to be a parody: The contrast between the original context of enunciation and the modern one is the way in which Lessing’s tolerance is finally checkmated.
