Fifty Bibles of Constantine

The Fifty Bibles of Constantine were Bibles in the original Greek language commissioned in 331 by Constantine I and prepared by Eusebius of Caesarea. They were made for the use of the Bishop of Constantinople in the growing number of churches in that very new city. Eusebius quoted the letter of commission in his Life of Constantine, and it is the only surviving source from which we know of the existence of the Bibles.^[1]
