of a large Scythian barrow in Ryzhanovka, among other projects. These investigations have brought one of the most outstanding archaeological discoveries of recent years: the discovery of richly accoutred burial of a Scythian ruler. Now, the works are carried out under the direction of Jan Machnik and the efforts are focused on the research into settlements located on the Dniestr River. It is possible thanks to the grants by the Committee for Scientific Research (KBN). Returning to its pre-war intentions, the PAU has also contributed to archaeological research being conducted in Greece. These investigations deal with the sequence of layers, unique in this part of Europe, in Cave No. 1 at Klisura (eastern Peloponnese), in which traces of habitation and palaeontological finds from the period of the last Ice Age occur. This research contributes to our understanding not only of the evolution of culture in Greece, but also of climatic and paleoecological changes over the last 100,000 years. The works are being conducted under the direction of Janusz Kozłowski, under research grants. They have borne fruit in the form of the publication of the results, jointly with the Greek Academy of Sciences and the PAU. Pursuant to the cultural cooperation treaty between Poland and Egypt, the PAU, in cooperation with the Institute of Archaeology of the Jagiellonian University, is participating in archaeological investigations in the Nile Delta.
