The world's oldest d20 die

In the world of tabletop gaming, few objects carry as much history and intrigue as the 20-sided die (d20). This iconic polyhedral die has shaped countless roleplaying adventures for decades. But have you ever wondered about the oldest d20 in existence?
Among the oldest dice ever discovered, the Egyptian d20 is a remarkable artifact that offers a glimpse into the past. In this article, we explore its origins, history, and the journey that led from ancient times to the gaming tables of today.
Did the d20 exist before D&D?
Yes, the 20-sided die existed long before Dungeons & Dragons. The icosahedron, the shape of a d20, was used in Ancient Hellenistic and Roman times, though for entirely different purposes. While the d20 has ancient roots, it was D&D that brought it into popular culture, making it a staple of tabletop role-playing games.

When was the 20-sided die invented?
The exact origins of the 20-sided die remain unknown. While the oldest surviving d20 dates back to between the 2nd century BC and the 4th century AD in ancient Egypt, there may have been even earlier examples that have been lost to time or are yet to be discovered.
Several other ancient d20s from the Roman era have been recovered, including the world’s most expensive d20, which is made of glass. Additionally, other icosahedral dice from the same period, including one crafted from faience, suggest that these fascinating objects were used in various ways long before modern tabletop gaming.
