Hannah Arendt in her essay “On Violence” (1969) says ‘Events, by definition, are occurrences?

... that interrupt routine processes and routine procedures…’ (1969:109). In light of this explain how the term “event” becomes dramatised in Sophocles’ Antigone as a violent action and violent circumstance-that might incorporate even further considerations from Arendt including: the “implement” and the effect of the interplay between the “ends” and the “means.”
