Optical Study of the Ryukyu Paintings
We conducted an optical study of the Ryukyu paintings at Okinawa Prefectural Museum & Art Museum on June 20-23, 2017. In order to investigate the depiction techniques and coloring materials, high-resolution color imaging and X-ray fluorescence spectrometry were applied for ten paintings held by the Okinawa Prefectural Museums and the Okinawa Churashima Foundation. Ryukyu-koku no zu, an important cultural property, held in Okinawa Prefectural Library was also investigated.
Many of the Ryukyu paintings have disappeared due to the warfare of World War II, and sufficient research has not been performed. We have conducted optical studies of the Ryukyu paintings located inside and outside Okinawa Prefecture since 2008. Optical study of the Ryukyu paintings will continue to be conducted in the future and the results will be published. We believe that the study is of great help in deepening the understanding of the Ryukyu paintings.
