The coat of arms of Germany is a symbol of Germany; the coat of arms feature an eagle. The colours of the coat of arms are similar to those of the flag of Germany (black, red and gold). It is the one of the oldest extant state symbols of Europe and is one of the oldest insignia in the world. Moreover, its history as an emblem began even earlier. To the Germanic tribes, the eagle was the bird of the god Odin.------------------------------------Official depictions of the eagle can be found not only in the federal coat of arms but also on the federal institutions flag, the standard of the President of Germany and official seals. These are designs by various artists of the Weimar period and differ primarily in the shape and position of the wings. A large and very plump version of the eagle decorates the chamber of the Bundestag, the German parliament, it is sometimes called "Fette Henne" (Fat Hen). In addition to the official depictions, artistic renderings of the federal eagle are permitted and have found their way onto coins, stamps and the letterhead of federal authorities.
