The eye

 

The Eye of Providence (or the all-seeing eye of God) is a symbol that depicts an eye, often enclosed in a triangle and surrounded by rays of light or Glory, meant to represent divine providence, whereby the eye of God watches over humanity.^[1][2][3] A well known example of the Eye of Providence appears on the reverse of the Great Seal of the United States, which is depicted on the United States one-dollar bill.
