MY first duty should be to make known the authorities for this history. But L'Averdy, Buchon, J. Quicherat, Vallet de Viriville, Siméon Luce, Boucher de Molandon, MM. Robillard de Beaurepaire, Lanéry d'Arc, Henri Jadart, Alexandre Sorel, Germain Lefèvre-Pontalis, L. Jarry, and many other scholars have published and expounded various documents for the life of Joan of Arc. I refer my readers to their works which in themselves constitute a voluminous literature, and without entering on any new examination of these documents, I will merely indicate rapidly and generally the reasons for the use I have chosen to make of them. They are: first, the trial which resulted in her condemnation; second, the chronicles; third, the trial for her rehabilitation; fourth, letters, deeds, and other papers.
