The volume analyses a specific motif within the medieval tradition of chess allegory originating from the influential treatise attributed to Jacobus de Cessolis, in which the chessboard represents the hierarchical structure of society and each piece symbolises a professional or social role. The study focuses on the representation of the physician among the occupational figures linked to the pawns and explains how moral instruction, professional duties, and ethical ideals were articulated through narratives associated with the game of chess. It also contextualises the broader dissemination of the Cessolis tradition, one of the most widely circulated didactic texts of the late Middle Ages, examining manuscripts, iconography, and the reception of the allegory in later cultural and historical interpretations of chess literature and social symbolism.
