Swiderian Culture - Development

Development

Three periods can be distinguished. The crude flint blades of Early Swiderian are found in the area of Nowy Mlyn in the Holy Cross Mountains region. The Developed Swiderian appeared with their migrations to the north and is characterized by tanged blades: this stage separates the northwestern European cultural province, embracing Belgium, Holland, northwest Germany, Denmark and Norway, and the Middle East European cultural province, embracing Silesia, Brandenburgia, Poland, Lithuania, Belarus, Central Russia, Ukraine and the Crimea. Late Swiderian is characterized by blades with a blunted back.

The Swiderian culture plays a central role in the Palaeolithic-Mesolithic transition. It has been generally accepted that most of the Swiderian population emigrated at the very end of the Pleistocene (10,000 BP uncalibrated; 9500 BC calibrated) to the northeast following the retreating tundra, after the Younger Dryas. Recent radiocarbon dates prove that some groups of the Svidero-Ahrensburgian Complex persisted into the Preboreal. Unlike western Europe, the Mesolithic groups now inhabiting the Polish Plain were newcomers. This has been attested by a 300-year-long gap between the youngest Palaeolithic and the oldest Mesolithic occupation. The oldest Mesolithic site is Chwalim, located in western Poland; it outdates the Mesolithic sites situated to the east in central and northeastern Poland by about 150 years. Thus, the Mesolithic population progressed from the west after a 300-year-long settlement break, and moved gradually towards the east. The lack of good flint raw materials in the Polish early Mesolithic has been interpreted thus that the new arriving people were not acquainted yet with the best local sources of flint, proving their external origin.
