The following part is devoted to the personality of the author and his work, the novel Der Zauberberg presents itself in the cultural and historical context of the time of creation and does not neglect the reception in the German environment. The benefit of this diploma thesis is to describe the reception of this novel in the Czech environment, where we will focus on the macrotexual (paratexty) and microtextual analysis of selected parts of the original and all Czech translations.
