The Bennu bird serves as the Egyptian correspondence to the phoenix, and is said to be the soul of the Sun-God Ra. Some of the titles of the Bennu bird were “He Who Came Into Being by Himself,” “Ascending One,” and “Lord of Jubilees.” The name is related to the verb “weben,” meaning “to rise brilliantly,” or “to shine.” The Bennu bird was the mythological phoenix of Egypt. It was associated with the rising of the Nile, resurrection, and the sun. Because the Bennu represented creation and renewal, it was connected with the Egyptian calendar. Indeed, the Temple of the Bennu was well known for its time-keeping devices.
According to ancient Egyptian myth, the Bennu had created itself from a fire that was burned on a holy tree in one of the sacred precincts of the temple of Ra. Other versions say that the Bennu bird burst forth from the heart of Osiris. The Bennu was supposed to have rested on a sacred pillar that was known as the benben-stone. The Egyptian priests showed this pillar to visitors, who considered it the most holy place on earth.
A large species of heron, nowadays extinct, occurred on the Arabian Peninsula in comparatively recent times; it may have been the ultimate inspiration for the Bennu. Reflecting this, the species was described as Bennu Heron (Ardea bennuides).
