Our modern (mis)understandings of the past are not mistakes but the products of changed historical conditions. We value in Gesualdo something his contemporaries could not have valued, because we know what they (and he) did not – namely, their future, which is now our past. That knowledge can hardly be erased from our consciousness.
So what interests us now bespeaks our condition and no one else’s. No amount of historical learning can replace new understanding with old understanding. All one can hope to do is add depth and detail to our misunderstanding. (That is where the sacred music and the instrumental music can usefully fit into even the most biased modern appreciation of Gesualdo.) If that seems a paradoxical thing to say, that has been precisely the intention. (739-741)
