Monologue has always been considered as a less dramatic element in drama. But Koltès has a keen interest in monologue and uses it heavily in his plays. Moreover, he is quite creative in maximizing its dramatic, narrational and lyric effect. The immersion and collisions between dramatic and non-dramatic attributes in Koltès’ s monologues brought about a clear change in the representation of dramatic conflict, the development of plot, and the existence of dramatic characters, thus turning drama into a modern "rhapsody" that contains heterogeneous elements but still retain its uniformity. Thanks to its unlimited cross-generic possibilities, Koltès’ s use of monologues shows that drama does have a great potential to break through its old conventions for a full self-liberation.
