The lion is a common charge in heraldry and the most beloved coat of arms animal. It traditionally symbolizes bravery, valor, strength, and royalty, since it is regarded as the king of the jungle. The lion's head is normally seen in profile. If he faces the viewer he is gardant (or guardant), and if he looks back over his shoulder he is regardant. These adjectives follow any other adjectives of position. The lions in the coat of arms of England are passant gardant. In French blazon this charge is called a léopard; a lion rampant gardant is a léopard lionné; and a lion passant with his head in profile is a lion léopardé. The position of the head thus determines his species. This practice leads some people to insist bitterly that the beasts in the royal arms of England are leopards, not lions. There is no right answer to this question. A lion (or other beast) coward has his tail between his legs. His tail may also be forked (queue fourchée) or doubled (double-queued); in the arms of the kingdom of Bohemia, the forked tail was originally an artist's flourish, but later became a distinctive and essential detail. The lion has been represented figuratively since the Stone Age. Ice age hunters depicted the lion this way in the cultural stage of the Aurignacian more than 30,000 years ago. The characteristic of the lion as the "king of the jungle" goes back to the influence of The Physiologus, an early Christian book about animal symbolism which spread into many cultures and generally had great influence in Western culture. The royal symbolism of the lion was repeatedly taken up in history, in order to claim power, for example by Henry the Lion. The ongoing fascination is apparent today by the diversity of coats of arms on which the lion is shown in various colors and forms.
