Second-century d20 sold by Christie's. I am not making this up, or exaggerating, or being in any way dishonest. It really is a twenty-sided die dating from the 2nd century AD with a series of symbols on the faces. Really.
Does anyone recognize any of the symbols visible from the picture? The circle-with-dot is the symbol for the Sun in astronomy and such, and the others look like they might be constellations. Does anyone know for sure?
Geekiness: older than you think.
