Anthony Vazquez/Sun-Times The Field Museum gave a glimpse into how scientists can analyze a 2,000-year-old portrait that can reveal ancient trade routes for painting materials and manufacturing techniques using state-of-the-art technology. Researchers can examine the way paint reflects, absorbs and emits radiation at different wavelengths by using a special camera that can capture light in the ultraviolet and infrared ranges beyond what can be seen with the human eye. The portrait examined Wednesday is thought to have been displayed in the 1893 World’s Fair and was later added to the Field’s collection. Researchers Giovanni Verri of the Art Institute of Chicago and Marc Sebastian Walton of Northwestern University are leading the effort to learn how it was made and what it can tell us about the period.
