Detail of centerpiece from the 8 foot x 100 foot mural, “E Pluribus Unum”, located in Baltimore’s legendary Lexington Market. Artist Bob Hieronimus, 1986. Eye in the Triangle: The eye in the triangle has been used by many secret societies and esoteric groups to symbolize the All-Seeing Eye of God. It is the Eye of Providence, or Spiritual Vision, and may also refer to humanity’s 6th sense, clairvoyance (meaning clear-seeing). Washington’s Watermark: between the eye in the triangle and the top of the Great Pyramid is a watermark designed by General George Washington for his stationery. It shows a woman standing by a plow and holding a pole bearing a liberty cap in her right hand and an olive branch in her left hand. The bird atop the seal is the raven found on Washington’s family coat of arms. It serves as Washington’s approval of the philosophy depicted on the reverse of America’s Great Seal.
