@Svevlad There is a term Kolovrat / Kolovorot in Slavic languages. There is a spinning burning wheel on Kupalo Night with four or six or eight arms in Belarus.
Kupalle in Belarus
I found a wheel with 8 arms on a historic piece kept in Belarusian museum (1914). On the top half between the leaves.
How arms on the symbol are bent at 90 degrees and the symbol is labeled as Kolovrat is a mystery. I guess it’s a creation of Polish painter Stanislaw who published a book in Krakow in 1923 . They symbol was popularised by neo-pagans in the 1990s. I can’t find any more information on this.
