Eye of Providence
The Eye of Providence is a symbol depicting the all-seeing eye of God in a triangle and/or surrounded by rays of glory. It can be a real Christian symbol (in which case, the triangle stands for the Christian Trinity), but it was also taken up by 18th-century Deists and Freemasons. In the 20th century, it was adopted as a symbol of Cao Dai.
