The 4500 year old bulk of the pyramid of Pharaoh
Khafra (Chephren) shields the sun to reveal a sun dog, a 22 degree
halo and a hinted upper tangent arc.
Ancient Egyptians recognised several manifestations of the sun god Ra, Ra-Herakhty
of the rising sun, Ra-Atum of the setting sun and Aten the solar disk. Strangely,
there is no acknowledgement of the sundogs or parhelia that
must at times have accompanied Ra on his daily journey across the sky.
