A total reverse of fortune, coming unawares upon a man who 'stood in high degree,' happy and apparently secure,-such was the tragic fact to the mediaeval mind. It appealed strongly to common human sympathy and pity; it startled also another feeling, that of fear. It frightened men and awed them. It made them feel that man is blind and helpless, the plaything of an inscrutable power, called by the name of Fortune or some other name,-a power which appears to smile on him for a little, and then on a sudden strikes him down in his pride.

Macbeth's deed is done in horror, and without the faintest desire or sense of glory- done, one may almost say, as if it were an appalling duty; the instant it is finished, its futility is revealed to Macbeth as clearly as its vileness had been revealed beforehand

The suffering and calamity are, moreover, exceptional. They befall a conspicuous person. They are themselves of some striking kind. They are also, as a rule, unexpected, and contrasted with previous happiness or glory. A tale, for example, of a man slowly worn to death by disease, poverty, little cares, sordid vices, petty persecutions, however piteous or dreadful it might be, would not be tragic in the Shakespearean sense.

The centre of the tragedy, therefore, may be said with equal truth to lie in action issuing from character, or in character issuing in action.

The story depicts also the troubled part of the hero's life which precedes and leads up to his death; and an instantaneous death occurring by 'accident' in the midst of prosperity would not suffice for it. It is, in fact, essentially a tale of suffering and calamity conducting to death.
