The “Eye of Providence” is a symbol displaying an eye often within a triangle and encircled with rays of light and/or with clouds. “It is sometimes interpreted as representing the eye of God watching over humankind (or divine providence).”  It has a long history, found in settings both secular and religious; a controversial symbol as there are various interpretations about its origins and meaning—some seeing it as good, and others associating it with evil.
Focusing on what we concretely can see, the “Eye of Providence” is commonly viewed on the back of $1 bills as part of the Great Seal of the United States, on the coat of arms of Brasłaŭ, Belarus and Kalvarija, Lithuania; the seal of the State of Colorado, The University of Mississippi, University of Chile, and elsewhere.
