English: The Arms of the Fraternity are described in heraldic terms as a black shield bearing hands and letters of gold as in our badge, around which emblems run what is known as a double tressure, flory counter flory, of silver.

The 'double tressure' alludes to the 'tie that binds,' the secrets, ideals, and aims of the Fraternity.

The black 'shield' was chosen not only because it is more effective than any other hue in line engraving (which was the chief use of the coat-of-arms), but also because it is the background of the badge.

The 'crest' consists of an owl surmounting Roman fasces. The owl was assigned by the Greeks to Pallas Athena as an emblem of her supernatural wisdom, and by the Romans to Minerva, Goddess of Wisdom. The 'fasces,' which the owl surmounts, was a term given to a bundle of elm sticks or branches bound together with leather thongs or lashes, and containing an axe with its blade projecting from the side. These were carried by 'lectors' (public officials attending Roman magistrates), and were symbols of power.

The colors of the Fraternity are represented by a garnet ribbon on the dexter side of the shield, and by a gold one at the left, from which, united below the shield, depends by a ring the Psi Upsilon badge. The supporters are two silver griffins, typifying watchfulness and strength.

The motto, selected from Plato, translates to: "Unto us has befallen a mighty friendship." For a Greek-letter fraternity, a Greek motto is necessary.
