Coat of Arms
The Coat of Arms has been modified twice since its inception in 1916.
Original
The original Coat of Arms consisted of a shield bearing the Lamp of Knowledge, three stars, and clasped hands. The shield was bordered by two representations of Hermes, messenger of the Greek gods, who held a large Greek letter Phi over the shield. A ribbon adorned the bottom of the shield.
1930 Redesign
As the National Fraternity expanded, the Coat of Arms was redesigned in 1930 to present a more professional image. The new Coat of Arms consisted of a shield bearing an open book and staff, three stars, and four clasped links. The shield was surmounted by the Lamp of Knowledge and adorned at the bottom with a ribbon upon which were embroidered Phi Sigma Pi in Greek.
1940 Redesign
The most recent change to the Coat of Arms came in 1940, resulting in a more highly defined version of the 1930 Coat of Arms, and one which could be more easily reproduced. This version is still used by the National Fraternity.
