This is one of the most amazing discoveries I have seen recently. The sheer weight of that stone is absolutely insane. I'm still a little stunned this was just discovered.
I would love to know what the people who made this were thinking. To create a work of art that detailed and massive just to bury 75% of it seems very odd. I'm sure there was a good reason to do it (in their minds at least), I'd love to know what that was.
