Indeed. Zrinski, you are probably familiar with the premise that the Hrvati/Croats of the 6th-8th centuries CE were a tribe of Slavic-Sarmatian synthesis. The nobility/military aristocracy were at first wholly Sarmatian. The Slavic element gradually came to dominate over the centuries until the S~ component was largely forgotten, as in several other European locales (e.g. Brittany).

I have the recent King Arthur movie, and though the acting and screenplay were somewhat cliched, I was quite pleased with the attempt to give a (compacted) historical treatment to the myth/legend/historical truth. I am convinced, by reading From Scythia to Camelot by Littleton & Malcor and Arthur the Dragon KIng by Reid, that the most crucial aspects of the story were of Sarmatian-Alanic genesis.
