Multispectral Imaging and the Voynich Manuscript
11th September 2024
Multispectral imaging is a way of capturing a digital image using non-visible wavelengths such as ultraviolet and infrared (click here to learn more). Where medieval manuscripts are concerned, UV imaging in particular can make faded or effaced text legible. This is because most medieval inks (including that used to write the Voynich Manuscript) have a significant iron component. This allows the ink to “bite” into the surface of the parchment rather than sliding off of it. When ink is scraped away or fades, the molecular bond remains, and the faded text may therefore fluoresce when exposed to UV bandwidths. This technology has proven invaluable in helping scholars read palimpsests and damaged manuscripts such as the Archimedes Palimpsest and the Syriac Galen Palimpsest. Could such imaging of the Voynich Manuscript help reveal its secrets?
