The article presents a few excerpts from the lost memoirs of Gabriela Puzynina, which were copied by hand by Mieczysław Rulikowski during the Second World War in 1940. The original manuscript, kept in the Przezdzieckis’ Archive, was destroyed in 1944, so these nine sheets of paper (1–6, 12–13), found now in Rulikowski’s archives, in addition to several other quotations from the memoirs previously saved by Czesław Jankowski, are a confirmation of the memoirs’ existence. The discovered fragment of Puzynina’s notes relates to the Vilnius theatre of the 1850s and 1860s. It also describes the circumstances in which Puzynina’s dramas were staged and shows the life of Vilnius actors and their social circles. The document from the middle of the 19th century mentions lesser-known theatrical events and brings a few emotional portraits of people from the past.
