Optical Information Persistence in Historical Oil Portraits: A BIMOD-Based Comparative Polarity Study of Mona Lisa and King George IV (OIP-HP Series)

This paper investigates the persistence of structured opticalinformation in historical oil portraits through reproduciblepolarity response testing using the BIMOD (Bodily InterferometricMagneto-Optical Discrimination) protocol. Two masterworks fromdistinct eras and artistic traditions are examined comparatively:the Mona Lisa (Leonardo da Vinci, c.1503-1506) and the portraitof King George IV (Thomas Lawrence, c.1820). Despite differences in artist, era, and stylistic tradition, bothportraits yielded consistent polarity-specific responses understandardized experimental conditions — identifying the Mona Lisaas 1S Hepatonia and King George IV as 2N Cholecystonia. Controlimages (uniform color fields, random patterns) yielded no response,confirming specificity. This study does not propose a mechanistic explanation but presentsempirical observations intended to stimulate interdisciplinaryinvestigation into optical encoding, perceptual physics, andhistorical painting techniques. The possible role of camera obscuratechniques in Leonardo's era is noted as a direction warrantingscientific analysis. Future research will focus on transitioning from human-mediatedpolarity detection toward objective micro-voltage (µV) scaleinstrumentation systems. Primary methodological reference: Yoon, D. (2026).
