Book of St Chad, Lichfield Cathedral, circa AD 730
If you like the St. Chad Gospels (which you should because they are awesome) you must check out the work of Bill Endres at the University of Oklahoma. He has been working with the St. Chad Gospels for years, digitized the book in 2010, and has done other notable work with it including Reflectance Transformation Imaging (RTI) and 3D imaging. He’s such a generous scholar, all of his work is available on his St. Chad Gospels website. Seriously, take the time to go over there and have a look, you won’t be sorry.
