The book is a monographic study of the world-known ancient Stone Age settlement - the Mezinskaya Late Palaeolithic site on the Desna River. The fully explored area of the site reveals remarkable remains of long-term dwellings, hearths, stone and bone processing sites and other economic and biological complexes. A great number of various tools and biological products, cult objects and jewellery made of stone and bone have been collected. The works of ancient art - sculpture, graphics and painting - found here are of exceptionally great value. On the materials of Mezinskaya and other sites a number of general questions of the history of the Late Palaeolithic, particularly in the Middle Dnieper basin, are highlighted. The book is of great interest to Russian and foreign archaeologists, geologists, art historians, students and all those interested in ancient history.
