tion of his shield and the ornaments of his helmet, and by the coat or surcoat which he wore over his coat of mail?
This surcoat had afforded another opportunity of decoration, and it had been decorated with the same signs that the wearer had painted on his shield, hence the term "coat of arms." This textile coat was in itself a product of the Crusades. The Crusaders went in their metal armour from the cooler atmospheres of Europe to the intolerable heat of the East. The surcoat and the lambrequin alike protected the metal armour and the metal helmet from the rays of the sun and the resulting discomfort to the wearer, and were also found very effective as a preventative of the rust resulting from rain and damp upon the metal. By the time that the closed helmet had developed the necessity of distinction and the identification of a man with the pictured signs he wore or carried, the evolution of armory into the science we know was practically complete.
