A Friar Bacon is punished (for writing too much) "He was ordered to be confined to his cell in the monastery and to be fed on bread and water for a considerable period"
The Popes and Science
Unfortunately, difficulties occurred within Friar Bacon's own order. It is not quite clear now just how these came about. The Franciscans of the rigid observance of those early times took vows of the severest poverty. There had been some relaxation of the rule, however, and certain abuses crept in. The consequence was the re-assertion after a time of the original rule of absolute poverty in all its stringency. It was Friar Bacon himself who had chosen this mode of life and had taken the vows of poverty. Paper was a very dear commodity, if indeed it was invented early enough in the century for him to have used it. Vellum was even more expensive. Just what material Bacon employed for his writings is not now known. Whatever it was, it seems to have cost much money, and because of his violation of his vow of poverty Roger Bacon fell under the ban of his order. He was ordered to be confined to his cell in the monastery and to be fed on bread and water for a considerable period. It must not be forgotten that this was within a century after the foundation of the Franciscans, and to an ardent son of St. Francis the living on bread and water would not be a very difficult thing at this time, since his ordinary diet would, at least during certain portions of the year, be scarcely better than this. There is no account of how Roger Bacon took his punishment. He might easily have left his order. There were many others at that time who did. He wished to remain as a faithful son of St. Francis, and seems to have accepted his punishment with the idea that his example would influence others of the order to submit to the enforcement of the regulation with regard to poverty, which superiors now thought so important, if the original spirit of St. Francis was to be regained.
