These two texts, though they comprise the oldest complete New Testaments, were written hundreds of years after the oldest extant manuscripts. Accordingly, virtually all modern translations of the Bible use the older manuscripts. Only the English Revised Version and American Standard Version, each written around 1900, used the Codex Vaticanus and Codex Sinaiticus.
The website for the Codex Sinaiticus claims that is the oldest substantial book to survive from Antiquity.
- Dates from the mid fourth century and originally included both Old and New Testaments plus the Epistle of Barnabas and the Shepherd of Hermas, all in Greek. It was found in Egypt, in a monastery library on the slopes of Mount Sinai (St. Catherine's Monastery), by Constantin von Tischendorf in 1859, and brought to St. Petersburg. In 1933, it was sold to the British Museum in London where it currently resides.
The Codex Sinaiticus is the oldest complete Bible to go online.
In 1975, the monks of St. Catherine discovered many parchment fragments. Among these fragments were twelve missing leaves from the Codex Sinaiticus.
