“Riddle of the Sphinx” aired on the PBS program NOVA, 1/19/10, where it was revealed and proven that the Sphinx was carved out of one existing stone up-cropping on the plain of Giza. This is a great victory for this writer, because I have contended that this was also the way the pyramids were constructed, from solid stone up-croppings. To give a better idea of how this was accomplished I built a model of the process. Below is a link to five photos that will shed more light on the subject. But what is interesting about my information is, that I formulated this was how it was done before any other scientist in the world. Besides writing, I do work on scientific mysteries.
