Were the ancient Egyptians the inventors of Dungeons and Dragons?
Short answer: no. But it's fun to imagine.
Dice have been around for millennia — the numbered cubes date back at least 5000 years in Asia, and are excavated from digs all over the ancient world. However, these three pieces in the Metropolitan Museum of Art are thought to be the oldest D20s ever found, hailing back to the Ptolemaic dynasty somewhere between 340 and 30 BC.
The facets are carved with what looks like Greek letters (which makes sense, considering Egypt's long association with Greece, including rule by a Greek family — the Ptolemies), but otherwise their provenance is largely unknown. They were collected by Reverend Chauncey Murch between 1883 and 1906 while he was on missionary in Egypt. He died in 1907, and his collection was donated to the museum by his estate in 1910.
We do know that the Ancient Egyptians played board and dice games, but it is unknown what these dice were used for. We're just going to go with D&D. It's more fun that way.
You can find the three dice, with zoomable images, on the Metropolitan Museum of Art's website here, here and here.
