Cemetery in Ostrów, site 21 as the example of multidirectional contacts of the Przeworsk culture – people living in the central part of the San River basin in the Early and Younger Roman Period

The cemetery in Ostrów, commune of Przemyśl, site 21 was discovered in 2013 during the construction works. The results of the study of this necropolis revealed more complex cultural and ethnic situation in the San River basin during the Roman Period. At least some part of the people using the mentioned cemetery originated from the eastern zone of the Przeworsk culture. Moreover, it is very likely that the cultural contacts with Sarmatian culture took place as well. The necropolis in Ostrów is also another site that confirms the growing amount of sites situated along the San River course in the period between the decline of the Early Roman Period and the beginning of the Younger Roman Period (i.e. phases B2-C1). It was the time of the expansion of the Przeworsk culture people into the Upper Tisa River basin
