In 1782, the Eye of Providence was adopted as part of the symbolism featured on the reverse side of the Great Seal of the United States. It was first proposed as an element of the Great Seal by the first of three design committees in 1776, and is thought to be the suggestion of the artistic consultant, Pierre Eugene du Simitiere, and at the time, was a conventional symbol for God’s benevolent oversight.
In his original proposal to the committee, du Simitiere placed the Eye over shields so as to symbolize each of the original thirteen states of the Union. On the version of the seal that would eventually be approved, the Eye is positioned above an unfinished pyramid of thirteen steps (again symbolizing the original States, but also incorporating the nation's potential for future growth). Such symbolism is explained through the motto that appears above the Eye, annuit cœptis, meaning "He approves [our] undertakings"
