Self-created Bird of the Sun
From the New Kingdom onward the Bennu is painted as a grey heron: long bill, long neck, two slender crest plumes trailing from the back of its head, sometimes crowned with the atef or the solar disk. In the theology of Heliopolis, the Bennu came into being of itself at creation and alighted on the benben, the first mound of land to rise from the primeval waters; its opening cry broke the silence and set time in motion. Its name shares a root meaning 'to rise, to shine' with the benben stone and with the benbenet, the capstone of the obelisk. It was called the ba, the manifest soul, of Ra, while also linked to the resurrected Osiris, binding sunrise and rebirth in a single figure.
Spell 83 of the Book of the Dead, 'spell for becoming a Bennu bird,' lets the deceased take the bird's form and declare himself the god of the ages arisen from the primeval flood. Heart amulets, emblems of self-renewal, frequently carry its image.
In Book II of the Histories, Herodotus reports the tale he heard at Heliopolis of the phoinix, a bird that flies in from Arabia once every five hundred years bearing its father's body sealed in myrrh for burial in the temple of the sun. This is the earliest full account of the Greek phoenix, and its source is the Bennu; relayed through Pliny, Tacitus, and Christian allegory, the image of the fire-reborn phoenix spread across Europe from that heron on the benben stone.
