“The Eagle is an emblem in heraldry, war, and legend. The eagle, borne upon a spear, was used by the Persians as a standard in the battle of Cunaxa, B. C. 401. The Romans used eagles of silver, or more rarely of gold, carried in the same way as standards. The Napoleon dynasty of France also adopted the eagle as their symbol. A double-headed eagle is the emblem of Russia, Austria, and Prussia."—(Charles Leonard-Stuart, 1911)
