The Dominican monastery at Limoges had been a "centre for historical study" for over a century, and Gui compiled numerous works of history (referred to by Gui as 'chronography'). These included the "Flores chronicorum," a universal history from the birth of Christ to his death in 1331, and various local histories, including accounts of the saints of Limousin ("Traité sur les saints du Limousin"), the abbey of Limoges ("Traité sur l'histoire de l'abbaye de St. Augustin de Limoges"), the priors of Grandmont ("Chronique des prieurs de Grandmont") and L'Artige ("Chronique des prieurs de l'Artige"), and the bishops of Toulouse ("Chronique des évêques de Toulouse") and Limoges ("Catalogue des Évêques de Limoges"). Additionally, he completed and significantly expanded the "De Quator in quibus Deus Praedicatorum ordinem insignivit," a historical treatise on the Dominican Order begun in the 1270s by Stephen of Salanhac, and uncompleted at the time of the latter's death in 1291. This was largely completed by 1311, although Gui continued to make minor additions until his death.
