Argumentative Old Git asks the question and El Pais provides the answer (hat-tip to By The Fireside): What happened before the Big Boom? Where does Latin American fiction come from? – Well, it seems it’s Latin American fiction all the way down.
There’s not many surprises though, I suppose, on the El Pais list (apart, naturally, from the names I don’t recognise, whom I’m assuming are all poets). Perhaps the Spanish are as parochial as we are, since I don’t see any Portuguese fiction on the list (but I can’t see where it says it’s being excluded either). I notice, of the six Spanish-language novels of that time-period on my [largely-failed] Latin-American readalong, five of them make the list (and as for the other, Yawar Fiesta, the author is represented by a different novel). In fact, I’ve read or got a surprisingly large number of them (I finally got hold of a collection of Horacio Quiroga stories; and I’ve just ordered some Eduardo Mallea).
