The phoenix is the sacred bird of myth, mentioned in Persian, Greek, Egyptian, and Chinese mythology. But once every thousand years, he spreads his wings and sings over a large mass of firewood, and when he is overjoyed by his song, he kindles a fire in his beak, and when it burns in the fire, an egg emerges from it, which immediately catches fire and burns. Another phoenix is born from its ashes. Phoenix is considered a symbol of immortality and longevity in most cultures. But some cultures have attributed other characteristics to him. The story goes that the bird lives for several hundred years before it dies by setting itself on fire. However, it then starts a new life from the ashes of the fire.
