"This great story-writer has constructed a literary world charged with a dense personal mythology, wonderfully invented, the starting point of which is always a village imagination raised to the highest power; I still remember the strong and pleasurable impression made on me in 1991 by La danza del jaguar (The Dance of the Jaguar), his first novel (...) Quintero is one of those "writers of before", and it is possible that, in the end, being so far removed from the lens of the media has benefitted him, because it has allowed him to accede to the ideal of certain purebred being pure text, being strictly a literature.".
