Portions of the Codex Sinaiticus (found in Sinai), which contains the oldest complete New Testament, will be available on the web by the University of Leipzig at www.codex-sinaiticus.net. The high resolution photos will include portions of the Gospel according to Saint Mark.
This manuscript is absolutely beautiful, as you can see in the photo above. The Greek handwriting is so tight that it almost looks like something printed from a computer. Yet it was all hand done.
Hat tip to Bobbie Marshall.
