B. Mozolevsky while commenting on the details of the world-famous Golden Pectoral he discovered in Tovsta Mogyla Kurgan, noted the size of the heads of the two main Scythians in the composition on it. He described them as unusually large. This kind of observation is in line with what we learned about the skulls of the Royal Scythians from Alexandropol Kurgan. Notably, other “ordinary” Scythians on the Pectoral have heads of a more “ordinary” size.
The “Royal Scythia, Greece, Kyiv Rus” book has more information and interesting insights into the scenes of the Pectoral.
