The eye represents wisdom and discernment.  The stars are in recognition of our six founders. The scroll is that of learning and bears the Greek letters, Sigma Theta Tau – the first letters of the Greek words storga, tharos, tima, meaning love, courage, honor. The pillars of stone at the right and left denote service, professional endeavor and strength of leadership. The lamp represents the lamp of knowledge. The motto on the banner is Sigma Theta Tau, the name of this international honor society.
