The history of literature and art history were not included in the programme of my historical studies (1960–1965). Naturally, all history professors would usually include something about art and literature in their lectures on “their” historical period, but not as a key element. Efforts were made to separate history and belles‑lettres (in its various manifestations). A strongly positivist vision of research and transferring its results to the general public was cultivated – which had its advantages in the face of ideological pressure on science in the People's Republic of Poland. Today, the function of both historical sources and statements on history are frequently taken on by literature, which I define very broadly: literary texts (sometimes even of clearly inferior quality), political texts, diaries and journals, journalistic reports, petitions, defence speeches, sometimes letters. Also interesting for the historian is the route these texts take to the reading or listening public, as well as their reception, sometimes their renaissance after many years. There is no need to add that with such an approach, the people who are the authors of even outstanding historical works are not necessarily those who are professional historians.
