Depiction
The Bennu was pictured as a grey, purple, blue, or white heron with a long beak and a two-feathered crest. Occasionally the Bennu was depicted as a yellow wagtail, or as an eagle with feathers of red and gold. In rare instances the Bennu was pictured as a man with the head of a heron, wearing a white or blue mummy dress under a transparent long coat. The Bennu was considered the “soul” of the god Atum, Ra, or Osiris.
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).
