[PREHISTORY IN THE WORK AND WRITINGS OF KAROL LIBELT].

Prehistoric archaeology constituted an important topic in the writings of Karol Libelt during the final stage of his work. As a result of several years' research and bringing up this subject in his texts, Libelt made notable achievements in the field of prehistoric archaeology. The most important of them are: description of archaeological discoveries in Czeszewo, participation in a dispute over prehistoric chronology with Stefan Pawlicki in 1871, and also one of the first descriptions of the Stone Age in the Polish literature. Thus Libelt should be considered as a pioneer in prehistoric research, particularly the Stone Age, in Poland. Apart from that, among his undoubted achievements was propagation of the theory of evolution, although with reservations, during the earliest stage of Darwinism's reception in Poland.
