Heraldry
Medieval Heraldry originated early in the 12th century in Europe and was used to identifying a individual in the battle. Armory originated in the 12th century in the Anglo-Norman lands and quickly spread to much of Europe. When the full face helm came into being it was difficult to identify armored men in battle and tournaments.
Heralds became experts at identifying knights by their arms. The next step was to start recording arms in Armorials. Since heralds were familiar with arms they were consulted by knights wishing to assume arms. The herald could tell the knight if their desired design that was used by someone else. Of course there are numerous examples of shields used by more than one individual.
