Abstract
As François Lambert experimented with religious identity in his passage from the Franciscan Observance to Lutheran Reform, he presents a valuable witness to the processes of identity formation and self-understanding in a period of religious turmoil that was still open to many different solutions. From 1522 to 1530 his choices led him from Avignon to Genève, Lausanne, Bern, Zurich, Basel, Wittenberg, Metz, Strasbourg, Marburg, in a life marked by projects of reform and moments of fear, illusions and delusions, success and failure. Lambert wrote a type of autobiography of this itinerary, which is traceable from his first work composed in Wittenberg until the very last letter that he wrote a few days..
