Arundel Herald of Arms Extraordinary is a supernumerary Officer of Arms in England. Though a royal herald, Arundel is not a member of the College of Arms, and was originally a private herald in the household of Thomas Fitzalan, Earl of Arundel. The first herald, John Cosoun, is known to have served the Earl both in Portugal in 1413 and later in France, where he attended his dying master in October 1415. The title was revived in 1727 as Herald Extraordinary. A badge was assigned to Arundel in 1958, derived from a badge of the Fitzalan earls of the fourteenth century, and a supporter in the arms of the present Earl Marshal of England. It is blazoned A Horse courant Argent in its mouth a Sprig of Oak proper.
