The Egyptian Sphinx had its beginning around this period and shows great astrological significance, with its human head on an animal's body (definitely a Lion). It could represent man on earth during 11,010 B.C. the Age of Leo the "sixth day," or may have been a monument built to symbolize the evolution of man from the animal or most likely the triumph of the human spirit over the beast."The riddle of the Sphinx of Gizeh, resting by the pyramids like a watchdog, has remained unsolved since the times of the pharaohs. The important point about this story is that the Sphinx was buried to its neck in sand thirty-seven centuries ago. This speaks for the very ancient origin of the Lion-Man even in that distant epoch. The ancient Egyptians called the monument 'Hu' or protector. From early times tradition held that a secret chamber existed under the Sphinx. Does 'Hu' guard a pre-deluge vault with records?" - "The Home of the Gods" Andrew Tomas page 114.
Hu (a god of wisdom) was one of Ra’s attendants, traveling the night voyage and had a place in the Hall of Two Truths, the judgment hall. Auf, (Efu Ra) was a ram-headed god who wore the solar disc and traveled at night through the underworld to reach the east in time for a new day, also was an aspect of the sun god Ra. His boat was crewed by the gods Hu, Saa and Wepwawet.
If the solution to the riddle is astronomical it may refer to the position of the sun on the horizon, or in the zodiac. The Zodiac of Denderah, oddly opening with the sign of Leo or Lion, registers the entry into a new cycle between 10,959 and 8,800 B.C.
