 As quoted in the bull of canonisation of St. Louis, the zeal with which he observed this fast was no longer a custom observed by Christians of great piety.It was then limited to the period from Saint Andrew until Christmas Day, since the solemnity of this apostle was more universal than that of St. Martin.When Pope Urban V ascended the papal seat in 1362, he simply forced people in his court to abstinence but there was no question of fasting.
