The design of the circle windows came from two Onondaga sources: One being "the Circle of Life", and the second being "The Circle Wampum". The circle was simplified for the use as a window. The original Circle wampum belt consisted of fifty strings of wampum joined at one end of each string to the perimeter of a large circle made of two intertwined wampum strings. Each single string represents one of the original fifty chiefs of the Haudenosaunee. The belt symbolized the invitation of the Peacemaker, the architect of the Great Law of Peace, to each of the fifty chiefs. they were to join hands in a circle to recognize that they are all of equal rank and that they should never forget their responsibilities to the people. The two intertwined strings represent the Great Peace that was established among the nations in the founding of the Great Law of Peace of the Haudenosaunee.
