Top 10 Surprising Facts About the World's Oldest Bible

1. You Can Read It — Right Now — Online

On July 6, 2009, the world's oldest Bible went digital. The 4th century Codex Sinaiticus manuscript ("the Sinai Book") is one of the most important texts in Christianity, dating to the time of Constantine the Great. Thanks to the Codex Sinaiticus Project, you can now see and read its raw animal-hide pages online. The photographs of the book's pages show not just the written text — an English translation accompanies the original Greek — but also skeletal imprints, insect bites, scar tissue and spilled candle wax. At nearly 800 pages, Sinaiticus is the largest edition of an ancient manuscript ever to hit the Web.
