Original image and licensingGutenberg's 42-line Bible, printed around 1454–55, is a landmark in the history of European printing and demonstrates the importance of religious texts in the early print market. The Bible was not the only driver of the technology: craft knowledge, capital, commercial demand and earlier printing traditions in East Asia belong in the wider history. Once established, European print culture helped carry religious controversy, scholarship, science and literature.
Religious demand was one important market for early printing, but the claim that one book alone made the press viable is too strong without further economic evidence.
This label distinguishes a factual historical record from the interpretation built around it. A well-documented event or influence pathway does not prove that no alternative history could produce a similar result. Grade note: the influence pathway is well documented; replacement remains a separate question
Commerce printed once the presses existed; the initial demand — the market that made the machine viable — was overwhelmingly the Book.
