The Alentejo is the landscape of heartbreak. Or at least it was to me. Even its trees are clearly loners, set apart from each other at distant intervals across miles of sere brown fields. The Alentejo is all about waiting, from its numbered cork trees, with their skinned underbellies between harvest years, to the fabled, and perhaps fictional, nun Mariana, writing from Beja to a lover who will never come back. The Letters of a Portuguese Nun have been awaiting an author, an answer, for three and a half centuries now. Once celebrated for sparking a revolution in the European epistolary novel, now considered out of fashion even in Portugal, they remain a literary enigma, the country’s Mona Lisa.
