The phoenix is a legendary bird. According to Greek mythology, it lives for five hundred years, then constructs a nest of spices, sings a final song, sets fire to the nest with a flap of its wings and burns itself to ashes. Out of the ashes a new phoenix arises.

At any one time, only one phoenix exists, so that to be the "Pheonix of the Creation" is to be one of a kind, a nonpareil, completely and wonderfully unique.
