This is a digitization of the famous Gospel of Nicodemus in the original Greek. This is the one where Christ descends into Hell and sets the sinners free. It was a big hit in the Middle Ages.

It was taken from a book published in 1876 by Tischendorff which can be found here:

The translation of the text was published in 1924 by M.R. James and can easily be found on numerous sites on the internet with a little bit of Googling. But a digitization of only the Greek portion of James translation can be found here:

There is also a Latin translation of the Greek in the Tieschendorff text which I have of scanned. It is actually better, much more vivid and colorful, so you might want to read that if you’re so inclined.
