Far from being a metaphor for racial tension, chess reveals world where people could engage as equals

Libro de axedrez, an illustrated 13th-century treatise on chess produced for King Alfonso X of Castile, features dozens of depictions of players from Africa, the Middle East and Asia that defy preconceptions of medieval social attitudes.
