While the Sphinx has always been a wonder, and certainly a mystery in modern times, its "mystical connections" probably began in the 1940's with the American psychic and prophet Edgar Cayce. In a trance he predicted that a chamber would be found under the front paws of the Sphinx which would contain a library of records originating with the survivors of the destruction of Atlantis. While this may sound far-fetched, intriguing bits of evidence have emerged.
Workers restoring the Sphinx located a doorway in its side. Old photographs show that this door was at least partially open at one time. The full extent of this opening have not been explored.

In 1995 workers renovating a parking lot near the Sphinx uncovered a series of tunnels and pathways, two of which dip further underground near the Sphinx. Bauval believes these are ancient and probably contemporaneous with the Sphinx itself.

While examining evidence of erosion, West's team used a seismograph around the Sphinx. They found evidence of hollow, regularly shaped spaces or chambers a few meters below ground between the paws and to either side of the Sphinx. To date, no further examination has been allowed.

It is very possible there are chambers under or near the Sphinx. Certainly the fantastic discoveries have not come to an end. Witness Kent Weeks' discovery of KV5 in 1989. As excavation has continued to the present, the largest and most elaborate tomb in the Valley of the Kings has been revealed, believed built by Ramses II as a tomb for his sons.
