Arnaud Baille/Sicre was a cobbler in the Comté de Foix in the late thirteenth and early fourteenth century. A number of details about his life are known to us through the Fournier Register, and Emmanuel Le Roy Ladurie's analysis of those records. His mother's heresy was uncovered by the Inquisition. Sybille was arrested, and was eventually burned at the stake after relapsing into Catharism. The family's property was confiscated. This left Arnaud embittered, as his mother's heresy had cost him his inheritance. He became an itinerant cobbler.
