Sarmatian is clearly non-Slavic element. It's one of the hordes of the East.
Ha, ha, if its not funny would be sad to say such a nonsense. Rome did destroyed your brain?
Spot this ...
This picture fails clearly to show Sarmats within Roman empire but giving good picture of the fact that Roman Empire bordered solely with Sarmatians in Europe. Now, if map is bigger you would see British islands included in Roman/Sarmatian realm same way Scandinavia was Sarmatian. Of course ALL was only Sarmatian realm before God even had idea of allowing Roman pest to be. So, you say Sarmats were non-European easterns? Semitic Iranians? First Scots, Picts were Semites? Natives of Poland, Serbia, Slavic world are Semites, Eastern peoples, Iranians? Czech Boika was Semitic?
Think again. You aren't that pro-Rome to spit on your own ancestors and heritage.
Man, what is White is White only because Sarmatian in origin. Sarmats were original native Europeans. No question about it for serious science. Only open question is were Sarmats those Neanderthals that were true original Whites of Europe or Sarmats came to be as first mix of those Neanderthals and incoming African Blacks that moved deeper in Europe after Ice age was over (there was multiple Ice ages and several times Balkan was Ice age refugium while civilization elsewhere in Europe collapsed).
What I sow on internet and considering primordial nature of Slavic languages that are base for all other European languages, I would tend to agree with Czech Jandacek, that Slavic/ie Sarmatian language was already formed 40.000 years in past. So, it is possible first orginal Whites of Europe- Neanderthals were first Sarmats or what is also working description Proto Slavs.
