The title of the thread is
Which COUNTRY has produced the greatest literature?, thus including Celan in the same bracket with Goethe, Schiller, Novalis and Hölderlin is an aberration, for he was born in
Bukovina to a German-speaking Jewish family, and he later studied in France and Romania, only to spend nearly his entire adult life in Paris, having French citizenship. The use of a German idiom and the recollection of his mother's tongue (which could be directly traced to the Holocaust) were the sole things that linked Celan to Germany, to that one country in which the official language was the language of his mother's assassins. You cannot atribute an author to a country merely on account of his choosen language.
While Cioran's assertion that
One does not inhabit a country; one inhabits a language. That is our country, our fatherland - and no other, is basically true, understanding that Celan was indeed inhabiting the German language (his use of language is unrivaled as far as I'm concerned regarding the German language in the XXth century, hence the dificulty translators are confronted with when trying to transpose his poetry into another tongue), but to imply that Celan was a product of Germany borders on the preposterous.
