When I was a student, I got the message – not from anything anybody said but from what was studied and mentioned – that the most valuable of Spain’s regional literatures was the Galician. The next in importance was the Catalan. And the least worthwhile was the Basque. I got the impression that all Basque authors of merit chose to write in Spanish, and that was that. Again, nobody ever said it. It’s just the conclusion I drew on my own.
It’s understandable because Basque is not even an Indo-European language, so it’s easier to forget there’s a literature in it. And then I discovered it wasn’t just any literature but absolutely stunning works of art.
