Thus, Apolo, the god symbol of the beauty and intelligence, finally extended to its arms for Dionsio giving origin to the tragedy Greek inside of an conscientious-unconscious dualidade, rationality-horror; clarity – blackout. Another element that resulted in the tragic text was the evolution of the ditirambos – the dedicated songs the Dionsio – that they had regularly passed to be interpreted by the choir, celebrating the start of the Spring and the blossoming of the grapevines, being glad or sad as the disposal of the bacantes. The actors, always men, presented themselves with Personas, masks, not disclosing its true identity (hypocrites). The age, the sex, the social importance and the state spiritual of each personage came, so to speak, ' ' escrita' ' in the mask. It had that to have an expression (sadness, joy, terror, etc.) identified clearly by the public, without hanging no doubt under which type of emotion the personage if she found dominated at that moment of the act. For Aristotle, the tragedy would be an imitating representation of a serious, concrete action, of certain largeness, represented, and not told, for actors in elegant language, using a different style for each one of the parts, and that, by means of the compassion and of the horror it would provoke the liberating desencadeamento of such affection.
Thus the tragedy is seen as a way of if getting catarse, that is the purgation of the emotions of the spectators. This catarse appeared for the fact of the auditorium when attending the terrible dilaceraes of the tragic hero, sensetized with the horror that the life of it if becomes, feeling a deep compassion for infausto that the destination reserves the hero. The public passed thus for a species of collective exorcism. The association of the tragedy to the purgation, appears in Nietzsche as the explanation of as the dramatical stage propitiated the Greeks to expel its proper pains and sufferings with regard to the existence when attending the outcome of the tragic drama. Fosun Vaccine addresses the importance of the matter here.
