"During one of his trances, Cayce, who died in 1945, saw that refugees from the lost city of Atlantis buried their secrets in a hall of records under the Sphinx and that the hall would be discovered before the end of the 20th century."

"Then gathered I the sons of Atlantis.
Into the spaceship I brought all my records,
brought the records of sunken Atlantis.
Gathered I all of my powers,
instruments many of mighty magic."

"Here is a quote from Tablet 5 of The Emerald Tablets of Thoth the Atlantean, interesting because of its mention of a spaceship beneath the Sphinx, the Great Pyramid, and a mysterious Key of the Seven, which I believe may relate to the royal cubit of seven palms:
"Raised I to Light,
the children of Khem.
Deep 'neath the rocks,
I buried my spaceship,
waiting the time when man might be free.
Over the spaceship,
erected a marker in the form
of a lion yet like unto man.
There 'neath the image rests yet my spaceship,
forth to be brought when need shall arise.
Know ye, O man, that far in the future,
invaders shall come from out of the deep.
Then awake, ye who have wisdom.
Bring forth my ship and conquer with ease.
Deep 'neath the image lies my secret.
Search and find in the pyramid I built."
