Ghostly faces and invisible verse found in medieval King Arthur text
From Fox News:
Ghostly faces and lines of verse previously invisible to the naked eye have been uncovered in the oldest surviving medieval manuscript written entirely in Welsh.
“The Black Book of Carmarthen,” dating to 1250, contains texts from the ninth through 12th centuries, including some of the earliest references to Arthur and Merlin.
