During his tenure Gui held eleven such 'general sermons' in the cathedral of St Stephen in Toulouse and the cemetery of St John the Martyr in Pamiers, at which he judged 627 individuals guilty of heresy. A further nine individuals were also judged guilty at smaller events. In total, the tribunals headed by Gui convicted 636 individuals of 940 counts of heresy. In the nineteenth century the consensus among historians was that Gui had organised the burning of more than six hundred individuals. However, more recent research has determined that no more than 45 of the individuals convicted by Gui (approximately 7% of the total) were executed, while 307 were imprisoned, 143 ordered to wear crosses, and nine sent on compulsory pilgrimages.
