“Venedi” on upper Vistula are proven as Balts, recently.“
Are there other proves besides this picture?
What about this (Getica by Jordanes, gothic historian of VI century):
“Within these rivers lies Dacia, encircled by the lofty Alps as by a crown. Near their left ridge, which inclines toward the north, and beginning at the source of the Vistula, the populous race of the Venethi dwell, occupying a great expanse of land. Though their names are now dispersed amid various clans and places, yet they are chiefly called Sclaveni and Antes. The abode of the Sclaveni extends from the city of Noviodunum and the lake called Mursianus to the Danaster, and northward as far as the Vistula. They have swamps and forests for their cities. The Antes, who are the bravest of these peoples dwelling in the curve of the sea of Pontus, spread from the Danaster to the Danaper, rivers that are many days’ journey apart….
After the slaughter of the Heruli, Hermanaric also took arms against the Venethi. This people, though despised in war, was strong in numbers and tried to resist him. But a multitude of cowards is of no avail, particularly when God permits an armed multitude to attack them. These people, as we started to say at the beginning of our account or catalogue of nations, though off-shoots from one stock, have now three names, that is, Venethi, Antes and Sclaveni. Though they now rage in war far and wide, in punishment for our sins, yet at that time they were all obedient to Hermanaric’s commands. “
So according to Jordanes Slavs (Sclaveni) are a subset of Venethi.
