The Deputy Grand Knight is second in command in the council. He assists the grand knight in the operation of the council affairs and is responsible for any duties assigned to him by the grand knight. He is also the council's program director advising the various service program directors.
The Deputy Grand Knight's jewel, the Compass, was also used by Columbus, the Mariner. The Knights of Columbus Compass, with its points being Charity, Unity, Fraternity and Patriotism, is known as the Compass of Virtue; its 32 flame-like rays represent the 32 virtues which may be possessed by men. It is hung from a purple ribbon. His robe is the same as the Grand Knight, but without the mantle.
