Bear Against An Eagle

The Romans used it on the standards of their armies. From this derives:
The late Byzantine Empire chose a two-headed golden eagle as its symbol. It is popularly that one head symbolised ancient Rome, and the other head symbolized "new Rome" at Constantinople. From this derives:
The two-headed eagle is the emblem of "Shqipëria" or Land of the Eagles, which is known in English as Albania (the legendary origin of the name written in The Tale of the Eagle)
After the fall of Constantinople, the Russian Empire took the two-headed eagle as its own symbol.
