Proto-Georgian, Ibero-Caucasian (Sumerian) sign of eternity and light, Life and the Sun. Borjghala - In Megrelian (aka Colchian) Borj means time and Ghala - little river. so Borjghala means the river of time. It is an eternal rotation of the wheel of the time. It was first depicted in Sumeria approx. from 4000 BC and in Georgia -from 3500 BC. this sign was spread from Georgia to the North to the Vikings. so this sign can be seen in the Old Swedish graves.
