Is it at all possible that this is the bird which is shown on the staff of the Shaman in the pit at Lascaux?
That was a type of pheasant. Some pheasants live to be almost 100 years old!
That bird could possibly be --- "a bird associated with crossing time", as the shaman is obviously in trance, and "below" in a pit.
(Enki's Absu, = waters under, or supporting, or "birthing-(?)~in~perpetuity"?)
Corbels at Puma Punku are 3 step, the corbel in the GP queen's chamber is 5 steps, perhaps each corbel indicates an age of mankind?
This might push back the dating of the "orb and wings with serpents" (Enki=serpent) depicted on all Temple lintels in Egypt.
The bird becoming associated with just a pair of wings, might be responsible for that image of the House of Sokar glyph showing only a pair of wings above the serpent of creation. . . . (Creation serpent = the middle nadi channel?).
If the poor bird became trans-temporal, only her "wings" remaining (slender venus figures also all missing their heads), [holding those spears of keratin, edged with keratin, matching on either side]
. . .
Then the God or personage depicted holding and walking between those "temporal place holder" wings might have been the god of the Vulture Shamen, the god responsible for moving the soul from the past, (one wing) to the present (the other wing) . . . as an act of rebirthing, as seen in the image in Andrew's book.
Could Sokar have been the origination point of the cult of Vulture Shamen, and of course the name would be far, far older!
Proto-sumerian graves were in the shape of a foot print, with aa staff on one side, and ??? also present (sorry, stress-brain potholes). Feet, hooves, sacred cattle, spiders on Nazca with the 3 serpents of creation navigating between them the high spider and the low spider as seen on the stone at Gobekli Tepi.
Thinking aloud, here, . . .
Perhaps this is a new temporal baseline?
Mind is the rider.
