I have published a number of columns in the past on RockArtBlog about game boards in rock art (see the cloud index at the bottom). This one is about an example attributed to the Romans from between seventeen and fifteen hundred years ago that was found in the Netherlands.
“A limestone object recovered from the Roman settlement of Coriovallum, now Heerlen in the Netherlands, has provided rare evidence for how people played board games during the Roman period. The object, preserved in Het Romeins Museum, carries a pattern of incised lines on a flattened surface. Archeologists long suspected a link to play, yet no known Roman or earlier European game matches the design.” (Radley 2026) This presented researchers with a fascinating mystery. Can they find out what game was played on an unfamiliar board from that long ago? “Researchers used AI to reconstruct the rules of a board game carved into a stone found in the Dutch city of Heerlen. The team concludes that this type of game was played several centuries earlier than previously assumed.” (Phys.org 2026)
“Coriovallum was a Roman town in the province of Germania Inferior founded under the reign of emperor Augustus (27 BC–AD 14) and inhabited until the fall of the Western Roman Empire in AD 476. The remains of Coriovallum lie beneath present day Heerlen.” (Crist 2026:112)
Although the artifact’s provenance, the details of its discovery have been lost it is believed to have been excavated in Heerlen during the late 19th or early 20th centuries. “Contextual dating, based on the typical archeological strata of Heerlen, places the creation and used of this board between 1,700 and 1,500 years ago.” (Carvajal 2026)
The flattened stone board has a pattern of lines engraved into the upper surface. “The engraving consists of a rectangle defined by a perimeter groove within which four diagonal lines intersect to form a kind of X shape, accompanied by a single straight horizontal line at one end of the rectangle, and apparently simple but enigmatic configuration.” (Carvajal 2026) This is really not how I would describe the design of the lines on the surface, but interestingly, instead of a series of similar boxes, pits or outlines the design essentially consists of a large rectangle divided up into differing sized rectangular and triangular spaces. The design is symmetrical with both ends the same.
These questions particularly interested an archeologist named Walter Crist. “Archeologist Walter Crist encountered the stone in 2020 in the collection of the Thermenmuseum – which has since been renamed the Roman Museum. The worked limestone slab, measuring 21 by 14.5 centimeters, was found in the ground in Heerlen in the late 19th or early 20th century. Heerlen was once the important Roman settlement of Coriovallum. Crist specializes in ancient games and was immediately intrigued.” (Phys.org 2026)
Crist assumed that playing a game on this board would leave microscopic wear marks that might point to directions of movement of pieces. “Crist examined the stone under a microscope. ‘Wear was visible on the lines of the stone, exactly at the places where you would slide your playing piece.’ He enlisted the help of researchers from Heerlen and Maastricht. Restaura restoration studio from Heerlen produced highly detailed 3D scans.” (Phys.org 2026) They found the traces they were looking for suggesting possible patterns on the stone surface.
The wear patterns that were detected apparently followed along the diagonal lines on the stone. “To test whether play could explain the wear, researchers combined archeological observation with artificial intelligence-driven simulations. The team used the Ludii system, a platform designed to model historical board games. Two automated players competed against each other on a digital version of the stone board. The simulations drew from many rule systems recorded for small Northern European games, including examples from Scandinavia and Italy. The results showed strong agreement between the observed wear and simulations based on blocking games. In this type of game players aim to restrict an opponent’s movement rather than capture pieces. The simulated play repeatedly concentrated movement along the same lines seen on the stone surface.” (Radley 2026) While the results of the artificial intelligence analysis seem to confirm gameplay, they could not actually replicate for sure the actual game, which Crist (2026:1) refers to as Ludus Coriovalli.
“The use wear on the stone was plausibly created through gameplay, moving playing pieces of a size and material composition consistent with examples common at Roman sites, including Coriovallum. - The fact that the observed wear pattern is only apparent in parallel with the incised lines suggests that those lines were meaningful for the action that produced abraded wear along them.” (Crist 2026:121) Although the wear on the stone surface was not as serious as the wear on the Monopoly board I played as a kid, it could be detected with microscopy. And the wear patterns suggested the possible movements of the pieces.
