Taking a break this week in the swapcast series we've been doing with Ben from UnchartedX, We take the time to respond to emails, which sparks some great discussion on the Serapeum and the pyramids and ancient, lost technology.

We then turn to the legends of a particular lost object which we have spoken of before, the legendary Shamir, which was said to have been able to cut and shape stone with ease. In some cases the Shamir itself was said to be a stone, but also maybe a living creature, a worm of some kind, or perhaps an herb or some other plant. Whatever the Shamir was, it seems clear that some ancient people could work stone in ways that we do not understand in modern times.
