Originating from the German Blasen, meaning "to blow," blazonry is the art of describing in technical language the objects or charges borne in a coat of arms, as well as the manner of arranging them on a shield. The term originated from blowing a trumpet to announce the arrival of a knight, or his entrance into the lists at a joust or tournament. The blast was answered by the heralds, who described aloud and explained the arms borne by the knight.
