Abstract: Victor Klemperer, has studied the perversion of German langage during the Third Reich. In april 1945, some pages of this Diary recall his travel of ten days through Germany. Many “key words” in these pages can be found again in some letters written by Rimbaud in Harar ; the same in his short “Diary” : “From Harar to Warambot”, in april 1891. The formal harmony of these pages of Klemperer, is as surprising as in this Rimbaud’s “diary”.
