The book that Alexis Díaz-Pimienta has written is a new book, in the full sense of the word: almost everything that is said in it, is said for the first time. And although the phenomenon it deals with is not new at all, it is unknown to many, even in the field of culture and scholarship, because there are hardly any bibliographical antecedents, and these, in any case, are very recent. In such a way that Díaz-Pimienta’s book comes to discover an authentic and portentous “new world”, in old times like the ones we live in when cultural discoveries seemed finished.
