Laser technology may unlock the secrets of the Book of Kells

21st century laser technology will be used over the next two years to analyze Ireland's famous Book of Kells, a 9th century gospel housed at Trinity College in Dublin. Experts hope that analysis of the pigments may shed new light on medieval Irish trade routes.

"A lot of what we have done before has been based on anecdotal reports of the materials that were used," said Robin Adams, the librarian of Trinity College, who hopes the exacting dot-by-dot analysis by laser will unlock secrets and help his staff preserve the book. "Essentially the laser bounces back, and you get a spectrum."
