42-line Bible

The Gutenberg Bible (also known as the 42-line Bible, the Mazarin Bible or the B42) was the first major book printed using mass-produced movable metal type in Europe. It marked the start of the "Gutenberg Revolution" and the age of the printed book in the West. Widely praised for its high aesthetic and artistic qualities, the book has an iconic status. Written in Latin, the Catholic Gutenberg Bible is an edition of the Vulgate, printed by Johannes Gutenberg, in Mainz, in present-day Germany, in the 1450s. Since its publication, 49 copies (or substantial portions of copies) have survived, and they are considered to be among the most valuable books in the world even though no complete copy has been sold since 1978.

In March 1455, the future Pope Pius II wrote that he had seen pages from the Gutenberg Bible, being displayed to promote the edition, in Frankfurt. It is not known how many copies were printed, with the 1455 letter citing sources for both 158 and 180 copies.

The 36-line Bible, believed to be the second printed version of the Bible, is also sometimes referred to as a Gutenberg Bible, but is possibly the work of another printer.

The Gutenberg Bible, an edition of the Vulgate, contains the Latin version of the Hebrew Old Testament and the Greek New Testament. It is mainly the work of Jerome who began his work on the translation in 380 AD, with emendations from the Parisian Bible tradition, and further divergences (the Paris Bible, one of many Bible translations in the Middle Ages, is also known as the "Thirteenth-Century Bible", "Old French Bible" or, in French, "Bible du XIIIe siècle").

"All that has been written to me about that marvelous man seen at Frankfurt [sic] is true. I have not seen complete Bibles but only a number of quires of various books of the Bible. The script was very neat and legible, not at all difficult to follow—your grace would be able to read it without effort, and indeed without glasses."
