Examining Ancient Texts In The Digital Age

From the Wall Street Journal: "Improved technology is allowing researchers to scan ancient texts that were once unreadable -- blackened in fires or by chemical erosion, painted over or simply too fragile to unroll. Now, scholars are studying these works with X-ray fluorescence, multispectral imaging used by NASA to photograph Mars and CAT scans used by medical technicians." "In the process, they're uncovering unexpected troves of new finds, including never-before-seen versions of the Christian Gospels, fragments of Greek poetry and commentaries on Aristotle."
