The article examines the work of Gerhard Johann Robert Hauptmann in the context of the problem of self-understanding associated with the continuous process of creative comprehension of his works created earlier. The aim of this work is to identify the world-wide modernist position of Hauptmann, derived from his anthropological logic. The research tasks correspond to this: to show the process of formation of new forms of subjectivity in the dramatist’s work; to substantiate Hauptman’s internal movement to self-understanding; to review his drama ‟Iphigenie in Aulis”, to see how a new conception of being is emerging in the depths of the former artistic system. The analysis reveals the modernist tendencies in Hauptmann’s work, associated with the creative process of individual consciousness – the renewal, reworking and redefinition of impressions from previously read texts of pen’s colleagues (in this case Plato, Jakob Böhme, Sigmund Freud and Ricarda Huch) and the reinterpretation of their own works in this regard. Hauptman, expanding his horizon of study, gives the goddess Hecate, whom his drama ‟Iphigenie in Delphi” is referred to, the creative power of Eros and presents these chthonic powers in the work ‟Iphigenie in Aulis” as a positive first. The heroine, having grasped this first principle in indestructible unity, passes a difficult path of spiritual enlightenment, acquires a new birth – the immortality the elderly writer thought in his consciousness.
