The story of how Codex Amiatinus made its way from Northumbria, a medieval kingdom in what is now northern England and southeast Scotland where it was created, to Italy, where it was given to the pope, is a fascinating one. After 1,300 years, the codex returned to England in 2018 for a four-month exhibit at the British Library. The history of what some consider to be the finest book in the world can be found at the British Library’s Medieval manuscripts blog. And a video with Dr. Claire Breay and Dr. Beth Harris talking about Amiatinus can be seen here.
You can also see the complete Codex Amiatinus (yes, all 2,060 pages – it’s amazing!) on the website of Biblioteca Medicea Laurenziana (the Laurentian Library) in Florence, Italy. Genesis begins on "Carta 11r" and Matthew begins on "Carta 805r."
