The authors introduce the outcome of a scientific conference 'Two theatres - two worlds' (10-12 May 2007), published in 'Konteksty'. Its fundamental iaim was to combining reflections on the accomplishments of the Reduta Theatre and the Centre for Theatre Practices 'Gardzienice'. A fitting occasion for such a double meeting was provided by the sixtieth anniversary of the death of Juliusz Osterwa (19 May 2007) and the thirtieth anniversary of 'Gardzienice'. The death of Osterwa, which, after all, ended the history of the Reduta Theatre, did not denote the end of the ideas, which he, Mieczysław Limanowski, and artists co-working with them attempted to implement. These ideas are to be found, interpreted and unravelled in their own ways in, i. a. the praxis and philosophy of 'Gardzienice'.
