TORONTO -- A carved rock found in 1991 by a Canadian professor and archeologist could be the oldest chess piece ever found.

In an published in October, University of Victoria professor John Oleson announced that a piece of carved sandstone that was found in southern Jordan at Humayma may be an ancient rook -- a castle shaped piece in the game.

The roughly 1,300-year-old stone is squat and rectangular, with 鈥渉orn-like projections鈥. Although Oleson mentions it does resemble other artifacts, such as a Nabataean betyl, which is an altar made out of a block of stone to evoke the gods of the ancient Arab nation, when he compared the rock carving to other early chess pieces, the parallels were 鈥渇ar more convincing.鈥

According to Oleson, the object has the same abstract shape that other early Islamic chess pieces had.

References to chess-playing can be found in Islamic texts as early as the seventh century AD, Oleson said, and the game was 鈥渧ery popular.鈥

The piece Oleson found is 鈥渘early identical鈥 to abstract rook pieces dating from later centuries that were found near or in Jordan.

鈥淪ince the Humayma object was found in a seventh-century context, if the identification as a chess piece is correct, it would be the earliest known physical example for the simplified, abstract design,鈥 said Oleson, 鈥渁nd possibly the earliest known example of a chess piece altogether.鈥

The history of chess dates back around 1,500 years and is thought to have originated in India, although the names and rules have changed several times over the centuries.

Oleson theorized that the spread of chess occurred westward from India along merchant and diplomat routes, and that it is 鈥渘o surprise that early evidence for it should be found at a site on the busy Via Nova Traiana,鈥 which is a Roman road that served as an important trading route.

A significant chunk of Oleson鈥檚 work has taken place in or around the Humayma site. Between , he and his team excavated the settlement centre over the course of seven field sessions. In the process, they excavated two farmhouses, a Roman fort, four Byzantine churches, and 鈥渁 Nabataean campground and three Nabataean and Late Roman houses.鈥
