Abstract: Who was Jean de Labadie (1610-1674)? If he had not existed, he might have been the ideal fiction of the modern migrant, setting out from the heart of Catholicism to reach the promised new land of America. And yet he did exist, and produced a huge body of writing, which is examined in this work.
