The symbolism of the Eye goes to such archaic distances that it is really difficult to say where it first appeared. The Eye of Horus from Egypt and the eyes of Odin from Scandinavia are one of them. Later the eye began to associate with knowledge as such, with divine illumination and foresight. The Masons have an eye enclosed in a triangle, the so-called Radiant Delta, which symbolizes the Great Architect who oversees the work of people from heaven.
