The latter portion of the 14th century saw the cuirass gradually come into general use in connection with plate armor for the limbs until, at the close of the century, mail was phased out among the nobles (e.g., knights) except in the camail of the bascinet and at the edge of the hauberk. The cuirass was almost universally worn throughout its lifespan as a form of armor. The globule form of the breast-armor of the Black Prince, in his effigy in Canterbury Cathedral, 1376, intimates that a cuirass (as well as a hauberk) is to be considered to have been covered by the royalty-emblazoned jupon (surcoat) of the Prince.
