Quartering is a method of joining several different coats of arms together in one shield by dividing the shield into equal parts and placing different coats of arms in each division.

Attributed arms are Western European coats of arms given retrospectively to persons real or fictitious who died before the start of the age of heraldry in the latter half of the 12th century. Once coats of arms were the established fashion of the ruling class, society expected a king to be armigerous. Arms were assigned to the knights of the Round Table, and then to biblical figures, to Roman and Greek heroes, and to kings and popes who had not historically borne arms. Individual authors often attributed different arms for the same person, although the arms for major figures eventually became fixed.
