The Ancient Romans Were Gamers: 2nd Century Glass d20 Sold for $17,925 [Dice]

We can only guess what the ancient Romans might have thought about the latest revision of the Dungeons and Dragons rulebook (super approachable; they'd love it!), but we do know they were gamers. That's because an incredibly old, incredibly valuable Roman glass d20 was sold at auction by the famous Christie's auction house. For $17,925. Historians know the symbols are Roman, but have yet to figure out which game for which it was used. Any guesses, Gizmodo readers/ancient gaming history buffs? [Christie's]
