I have long ceased to be amazed by the key correspondences that exist in the symbols that man has developed down the ages, seemingly almost regardless of the cultural contexts in which they arise. Certain themes never seem to go away. The Old Testament account of man and his relations — with God and the other partners in the great hierarchy of being — the classical philosophical, and the Christian all see the same thing, and articulate it in remarkably similar language. This tells me there is a "seam" of God's Truth that perennially runs through the world; and noetically and spiritually sensitive people of all times and places notice things like that.
C. S. Lewis has a great appendix (in The Abolition of Man) that provides further details of this phenomenon.
To God be the Glory!
