Glass roman dices?

[fwg]

When did cubes replace knuckle bones?

The cubes and bones were used for different dice-games. While children are often depicted playing with astragaloi (knuckle-bones), 'conventional' dices are often associated with gambling (of adults).

And there are some Roman glass dices (I have to check in my picture archive, but I think at least in the Landesmuseum Stuttgart, germany), as well as there are ones made of lead crystal.

All the best,
