During the first century AD, Phoenix was mentioned 21 times by ten authors. From all these sources it appears that the myth of Phoenix originated in ancient Egyptian civilization and was later spoken of in Greek, Roman and Christian civilizations, respectively. Among the Egyptians, the myth of Phoenix was originally the myth of the sun rising again at dawn after each night, and the name of the city of Heliopolis in Herodotus must have been related to this. The Egyptians consider the phoenix a sacred bird, which is very rare. According to the people of Heliopolis, the phoenix appears in Egypt once every 500 years after the death of the previous phoenix. There are only a few pictures of this bird, and as can be seen from its shape and size in these pictures, the wings and jump are red and yellow are golden, and its general size is like an eagle. A strange story is told about the work of this bird, and that is that this bird brings its father's body, which is covered with a kind of fragrant plant gum, all the way from the Arab land to the Temple of the Sun and buries it there. It is said that in order to bring a corpse, first it makes a gum large enough to carry it, then it empties it and puts the corpse in it and closes its mouth with fresh gum, and then the bullet, which is correct. It has regained its original weight, is brought to Egypt, and while the entire surface of the bullet is covered with gum, it is placed inside the Temple of the Sun, as mentioned.
