The author of this volume was sent, in 1882, to the good city of Nantes as United States Consul. While resident there he entered upon the investigation which resulted in this volume. He obtained access to the original records of the trial in the archives of the department, and made a photographic copy of one of its manuscript Latin pages which is shown in its proper place. The trial of Gilles de Retz took place in the château of Nantes, sentence was pronounced at the Place Bouffay, and he was executed on the Prairie de la Madeleine, the exact locality being now occupied by the Hospital of St. Anne. The author procured photographs and drawings of some of these localities, which will appear in this volume. * * * * * Monsieur Charles Perrault was the author of the story of _Bluebeard_. He was born at Paris, January 12, 1628. His father was an advocate, originally from Tours. He was the youngest of four brothers: the oldest, Peter, was destined for the Bar, but became the Receiver-General of Finances under Louis XIV. and his Prime Minister Colbert, though he afterwards fell out of favour and died in poverty; Claude studied medicine; and Nicholas, theology. Charles was taken up by Colbert and made Superintendent of Public Buildings throughout the kingdom. While in this position, the erection of the Observatory and the reconstruction and completion of the Palais du Louvre were determined upon. Plans for these buildings were to be decided by competition, and the renown of the name of Perrault is greatly increased by the fact that Charles’s brother Claude, although educated as a doctor of medicine and not as an architect, designed plans which, after much discussion and investigation, extending even to Rome, were finally adopted by the King and his Minister. Charles Perrault became a member of the Academy--one of the “Immortal Forty.” He introduced many improvements into their methods, the principal of which was for securing the attendance of members, and a continuance of, and devotion to, the work of preparing the great French Dictionary. An episode in his life, covering several years, was his poem of _Le Siècle de Louis le Grand_ and the parallel between the ancients and moderns, which produced a discussion among the most brilliant writers of France. Boileau, Racine, La Fontaine, Longpierre, Buet, Arnauld, and other illustrious champions took up the cudgels against Perrault and Fontanelle, and in favour of the ancient classic heroes.
