context: Serteja-Rudnya pottery is one of the first stone-age pottery traditions introduced in Western Russia. Its pioneer users were probably Mesolithic groups that lived in a small area of ​​Pskov south of the Valdai Plateau and in the eastern Baltic in the river valleys of the Väinjoki, Dnieper and Lovat. They adopted the ceramic tradition before 6300 BC, when the Serteja pottery (, or) skill was learned in a limited area bounded by the Väinjoki, Dnieper and Lovat. The name of the pottery dates back to the Serteja River () flowing next to the settlements or the nearby village () where the earliest pots were found. The groups ceased production of Certeja pottery around 5300 BC. and then continued with Rudnja pottery (, or, Rudnja village). These traditions, previously considered separate, can be considered as successive stages of the same tradition. Rudnja pottery production ceased around 4500-4400 BC. The ceramic tradition marked the beginning of a new Stone Age cultural period in the region, called Russian Neolithic and Finnish literature the Subneolithic Stone Age. [1] [2]
