Eagle (heraldry)

Examples of heraldic eagles of the 13th to 16th centuries, from Hugo Gerard Ströhl's Heraldischer Atlas

The eagle is used in heraldry as a charge, as a supporter, and as a crest. Heraldic eagles can be found throughout world history like in the Achaemenid Empire or in the contemporary Republic of Indonesia. The European post-classical symbolism of the heraldic eagle is connected with the Roman Empire on one hand (especially in the case of the double-headed eagle), and with Saint John the Evangelist on the other.
