It is the two Greek Gods. Apollo is the God of order, wisdom, beauty and Dionysiac is God of disorder, stupidity, ugliness. Both are diametrically opposite in nature. The author Fredric Nietzsche has compare and contrast between the dream and intoxication. In dream, if it is good then you want to continue your dream but in intoxication the dream is not in your control. The author concern is about art. How any art can be sublime or beautiful? If the art is created by mixing or combining two kind of characters i.e. of Apollo and Dionysiac then it will be a sublime art. It also deals on aesthetic ( how people treat beauty). the essay says that aesthetics has been stagnant. The author also analyzes history of art from Greek civilization to Modern history. In every civilization after Greek there was not good quality of duality.
