THE following extraordinary account of the «Cause Célèbre» of Urbain Grandier, the Curé of Loudun, accused of Magic and of having caused the Nuns of the Convent of Saint Ursula to be possessed of devils, is written by an eye-witness, and not only an eyewitness but an actor in the scenes he describes. It is printed at «Poitiers, chez J. Thoreau et la veuve Ménier, Imprimeurs du Roi et de l'Université 1634.» I believe two copies only are known: my own, and the one in the National Library, Paris. The writer is Monsieur des Niau, Counsellor at la Flèche, evidently a firm believer in the absurd charges brought against Grandier.
