A tragic hero is a character (often the protagonist) who exhibits a tragic flaw or fatal flaw, which eventually leads to his or her demise. The concept of the tragic hero was created in ancient Greek tragedy and defined by Aristotle and others. Usually this includes the realization of fatal flaw, which results in catharsis or epiphany. The tragic flaw is sometimes referred to as an Achilles' heel after the single fatal flaw of the Greek warrior Achilles. (held by his heel while dipped in the River Styx).
Expressionism An artistic theory or practice of the late 19th and early 20th centuries in which • the subjective or subconscious thoughts and emotions of the artist, the struggle of abstract forces, orthe inner realities of life are presented by a wide variety of non-naturalistic techniques that: include abstraction, distortion, exaggeration, primitivism, fantasy, and symbolism. It arose as a reaction against complaints of materialism, complacent bourgeois prosperity, rapid mechanization and urbanization, and the domination of the family within pre-World War I European society.
In forging a drama of social protest, Expressionist writers were concerned with general truths rather than with particular situations; hence they explored the predicaments of representative symbolic types rather than of fully developed individualized characters. Emphasis in Expressionist drama is laid not on the outer world, which is merely sketched in and barely defined in place or time, but on the internal, on an individual's mental state. The leading character in an Expressionist play often delivers long monologues couched in a concentrated, elliptical language.Expressionism is the tendency of an artist to distort reality for an emotional effect.
