Straddling a small corner of Spain and France in a land that is marked on no maps except their own, the Basques are a puzzling contradiction—they are Europe's oldest nation without ever having been a country. No one has ever been able to determine their origins, and even the Basques' language, Euskera—the most ancient in Europe—is related to none other on earth. For centuries, their influence has been felt in nearly every realm, from religion to sports to commerce. Even today, the Basques are enjoying what may be the most important cultural renaissance in their long existence, as displayed by new cookbooks like chefs Alexandra Raij and Eder Montero's The Basque Book and restaurateur Jose Pizarro’s Basque.
