The Codex Sinaiticus open to the Gospel of John

Handwritten over 1,600 years ago in the middle of the 4th century, the Codex Sinaiticus contains the Christian Bible in Greek.
The book, which originally comprised over 1,460 pages, also contains the Old Testament text, known as the Septuagint.
The book owes its name (and its continued existence) to the place where it was preserved for centuries —St. Catherine’s Monastery near the foot of Mount Sinai in Egypt.
The Codex Sinaiticus is one of the two earliest sacred manuscripts that contain the full canon of the Christian Bible in one volume. Prior to its production, ancient scribes created separate books containing only a few texts.
