The Vessels Proof
Cairo Museum
Beneath the earth, below the base of the Sakkara Step Pyramid, Imhotep his builder and designer quarried out almost three miles of stone and built a series of corridors and inner chambers.
He decorated some of the chambers with blue enamel tiles, as far we know the first ever made by man, a proof of his advanced knowledge of alchemy.
In addition to all this, some thirty thousand stone vessels of the utmost perfection were found in these subterranean chambers. There are unique and enigmatic hard stone vessels, made of slate, diorite and basalt. Some of these materials are harder than iron. No sculptor today would even attempt to work with such material.
One wonders how could they have been carved? Their design is extremely beautiful and impossible to carve. No tool marks are found on their surfaces. They must have been cast in molds, in accordance with the indications suggested by the Irtysen Stele at the Louvre gallery.
