Re: New Tomb in Egypt.
Most won't have heard of them, but anyone with a modicum of research into the Philosopher's Stone knows about them.
And by the way don't believe the Billy BS in that article.
The lamps were powered by the Stone, nothing else. The Stone provides massive quantities of energy.
The "Mercury" that is referred to in alchemy is not the metallic element Mercury. It is an allegorical term used for a number of things. Primarily it refers to the distillate from the first part of the "Great Work", a clear liquid with specific properties. But alchemy has a habit of deliberately confusing readers to throw the dumb masses off the scent so "Mercury" can refer to other things too in certain circumstances.
Rest assured though that the liquid metallic element Mercury is not used in alchemy or in the creation of the Philosopher's Stone.
The Egyptians had the Stone, clearly, and used it to create large amounts of gold and to perform other wonders. Jesus also had the Stone, by which he could heal other people miraculously and survive being crucified. The Stone is largely kept hidden lest it leak out to the masses, because if that happens society as we know it would collapse. Banks, pharmaceuticals, conglomerates of all kinds would go bust over night. No-one would need them anymore.
