The Phoenix is a mythical bird, the myth of which was very popular in Ancient Egypt, and which perhaps had its origin even before the proto-dynastic period. Blessed with an extremely long life, at the end of its life, the phoenix would spontaneously combust into a pile of ashes, before rising from the ashes as a new, baby phoenix to begin its life again. The myth of the Phoenix is an example of the powerful theme of rebirth, so popular in mythology, which can be seen (especially in Egyptian mythology) in the tale of Isis and Osiris.
Also, the phoenix is the symbol on the great seal of the city of Atlanta. Captioned with the Latin phrase, "resurgens" (being reborn), the phoenix symbolizes Atlanta's transformation from a casualty of the Civil War to a great American metropolis.
