More than 1,600 years after it was written in Greek, one of the oldest copies of the Bible will become globally accessible online for the first time this week.

From Thursday, sections of the Codex Sinaiticus, which contains the oldest complete New Testament, will be available on the Internet, said the University of Leipzig, one of the four curators of the ancient text worldwide.

High resolution images of the Gospel of Mark, several Old Testament books, and notes on the work made over centuries will appear on www.codex-sinaiticus.net as a first step towards publishing the entire manuscript online by next July.

Ulrich Johannes Schneider, director of Leipzig University Library, which holds part of the manuscript, said the publication of the Codex online would allow anyone to study a work of “fundamental” importance to Christians.
