This is an ivory game box and pieces found in a sarcophagus in Thebes (Egypt) and dating back to 1635-1458 BCE. This particular one is on display at the Met Museum in New York but I had the intention of posting a similar one that can be admired at the Beirut National Museum; and that is in better condition as it does not have modern wood panels to reconstruct it. Unfortunately I couldn’t find good pictures of it.
Anyway this box also serves as the board for two games: Twenty squares on one side, in which the players had to race towards the central square; and Senet on the other, another racing game. The two weird looking pieces that are different from the game pieces are knuckle bones and were used as a dice. If you’re interested in learning more about the games, the Met has a great blog post about it which you can find here.
