Eagle, the Emblematic
The Etruscans were the first who adopted the eagle as the symbol of royal power, and bore its image as a standard at the head of their armies. From the time of Marius it was the principal emblem of the Roman Republic, and the only standard of the legions. It was represented with outspread wings, and was usually of silver, till the time of Hadrian, who made it of gold. The double-headed eagle was in use among the Byzantine emperors, to indicate, it is said, their claim to the empire both of the East and West. It was adopted in the fourteenth century by the German emperors, and afterwards appeared on the arms of Russia. The arms of Prussia are distinguished by the black eagle, and those of Poland bore the white. The white-headed eagle is the emblematic device of the United States of America, is the badge of the order of the Cincinnati, and is figured on coins. Napoleon adopted the eagle for the emblem of imperial France; it was not, however, represented in heraldic style, but in its natural form, with the thunderbolts of Jupiter. It was disused under the Bourbons, but was restored, by a decree of Louis Napoleon, January 1, 1852.
