Abstract
The study focuses on fasting as a means of recovering God’s grace, an act which was frequently ordered by authorities throughout the European Middle Ages. Crop failure in particular, as well as the famine which regularly resulted from it, were countered by fasting lasting several days. The famine of the years 805 to 806 is a special case of collective asceticism focussed on a distinct geographical entity and carried out using suitable rules e.g. fasting, prayer, alms-giving etc. At the same time it is shown to be a paradigmatic example of medieval crisis management. In cases such as these, renunciation seems to have been a sort of religiously motivated inward-looking self-compulsion. Consequently asceticism of this type can be regarded as the product of an external compulsion which seeks to mediate the world of events through a collectively established religious order.
