Eye of God
The Eye of God is an equilateral triangle with a single eye inside it and almost always with rays emanating from it.
It symbolizes the omnipresence and omniscience of God, who watches over all things. It is also associated with the Trinity (which the triangle symbolizes in itself).
Historically, representations of an eye tended to be avoided because of the association with the Evil Eye (a widespread and ancient European superstition). No medieval example of the Eye of God has yet been found. A rare Renaissance example of it appears above Christ's head in the Supper of Emmaus painted for the Carthusians in 1525 (shown at right).
The symbol has been connected with Masonic ritual, probably because medieval masons' guilds were foten dedicated to the Holy Trinity. In the 18th and 19th centuries it was used in Courts of Justice to remind judges of their responsibilities. The Eye of God appeared above the altar of the St. Aloysius church in London, which was built by French Catholics in 1808 but destroyed in World War II.
