Gutenberg Bible

The Gutenberg Bible, also known as the 42-line Bible, the Mazarin Bible or the B42, is the earliest major book printed in Europe using mass-produced metal movable type. It marked the start of the "Gutenberg Revolution" and the age of printed books in the West. The book is valued and revered for its high aesthetic and artistic qualities and its historical significance. The Gutenberg Bible is an edition of the Latin Vulgate printed in the 1450s by Johannes Gutenberg in Mainz (Holy Roman Empire), in present-day Germany. Out of either 158 or 180 copies that were originally printed, 49 survive in at least substantial portion, 21 of them in entirety; of these, the copy with the earliest visible print date is marked as 15 August 1456. They are thought to be among the world's most valuable books, although 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, displayed in Frankfurt to promote the edition. The 36-line Bible, said to be the second printed Bible, is also sometimes referred to as a Gutenberg Bible, but may be the work of another printer.
