In becoming fellowship with the Lion, the EAGLE appears in the earliest English Rolls and examples of Arms. The Royal bird, however, does not occur in English blazon so frequently as the Lion; and his appearance often denotes an alliance with German Princes. A Roll of Arms (printed in “Archæologia,” XXX.) of the year 1275 commences with the Shields of the “EMPEROR OF GERMANY,” and of the “KING OF GERMANY,” which are severally blazoned as,--“_Or, an Eagle displayed having two heads sa._,” and, “_Or, an Eagle displayed sable_.” In York Cathedral, in stained glass, there are Shields with both the double-headed and the single-headed Eagles, all of them German, which may be considered to have been executed before the year 1310. In the north choir-aisle at Westminster, the Shield (now mutilated) of the Emperor FREDERICK II. is boldly sculptured by an heraldic artist of the time of our HENRY III., No. 200; here the Eagle had one head only. The German Emperors naturally adopted the Eagle for their heraldic Ensign, in support of their claim to be successors to the Roman Cæsars; and the Russian Czars, with the same motive, have also assumed the same ensign. The Eagle having two heads, which severally look to the dexter and the sinister, as in No. 201, typified a rule that claimed to extend over both the Eastern and the Western Empires; as the Eagle with a single head, No. 202, might be considered to have a less comprehensive signification. The Eagles of the Princes of Germany are frequently to be found, blazoned for them, in England.
