The emblem was developed from the Crest and Coat of Arms of the family of the founder of the School, Bishop Hale. The School Coat of Arms consists of the head of a black swan at its crest resting on a bar of two blues, sitting above a navy blue shield with a cross-band of Cambridge blue. In the upper half, there are three cinquefoils in gold and blue. The three florets on the escutcheon signify the chivalry of the old Knighthood - the manly life, the pure life, the belief in God. In the lower half, the figures 1858 indicates the year the School was founded. "Duty" has been chosen as the School's motto. It represents a responsibility to one's community and country, above and beyond mere self.
