This is as likely a magical object as a gaming die. Glass would have been expensive for a mere gambling device, whereas bone dice were cheap. It's a Platonic solid found in Egypt, the epicenter of Neoplatonism. And the symbols on the sides are astrological.

Magical, in the sense of an Oracle casting a prediction. Which makes it pretty much the same as a D&D dungeon master rolling to determine the outcome of an event, except the players (and maybe the DM) believed it was real.

Could have been rolled as an oracle. Although glass strikes me as not the best material for that. Especially ancient glass that didn't have all of the chemical strengtheners that modern glass does

It might have been just an object of contemplation. Like, you can see how all of the heavenly bodies fit snugly into a perfect geometric figure and just wonder at it.

If there's any rhyme or reason to how the symbols are arrayed on the sides, it could have been a mnemonic or instructional device for casting horoscopes.

And, while it's probably too opaque to have been used for scrying, there's that too.

Wonderful. You can get so much Maths out of probability. The fifth most popular page on my personal Web site is http://sohcahtoa.org.uk/pages/rolling-two-dice-experiment.ht...

Off-hand, I would say you can't use chi-square unless you rolled at least 360 pairs of dice. Chi-square assumes a normal distribution and the rule-of-thumb you need at least ten hits and ten misses before the sample distribution approaches normal.

We are getting there (250 rolls now), I'll put the extra throws up. Your finding may come as a surprise to many geneticists however...

I think the ethics of trading such goods (at high prices) are bit questionable. It is a piece of local cultural heritage which more than likely was acquired in a more or less exploitative way.
