Examines the luminous carbuncle as a literary motif in medieval French romances set in classical antiquity. Drawing connections with lapidary traditions, the study considers the gem’s reputed ability to shine in darkness and its placement on towers, tents, helmets, and dragons’ foreheads. Its brilliance serves both practical narrative purposes, such as nocturnal illumination, and symbolic ones associated with exceptional knowledge, heroic status, and royal power. The discussion explores how romance transforms inherited knowledge about precious stones into literary imagery.
