A possible approach to the oeuvre of Mati Unt (1944–2005) has to do with psychoanalysis. Mati Unt’s interest in psychology and psychiatry developed during his student years at the University of Tartu, reaching its height during the theatre reform of the 1960s–1970s. A psychoanalytical substrate can be observed in both Unt’s prose and drama, as well as in his stage productions. The analysis is based on C. G. Jung’s theories and Unt’s creative interpretation of Jung’s views. Also, some light is thrown on how Unt’s interest in psychoanalysis was kindled by his sensitive nature and some facts of his personal life.
