The Apollonian and Dionysian is a philosophical and literary concept, or dichotomy, based on certain features of ancient Greek mythology. Many Western philosophical and literary figures have invoked this dichotomy in critical and creative works. In Greek mythology, Apollo and Dionysus are both sons of Zeus. Apollo is the god of the Sun, of dreams and of reason, while Dionysus is the god of wine, ecstasy and intoxication. The Greeks did not consider the two gods to be opposites or rivals, although often the two deities were interlacing by nature.
