Human stakes
Printers, scribes, readers, patrons, and religious institutions all stand before the same change, whether as opportunity, threat, or astonishment.
Historical event
The Gutenberg Bible is completed in Mainz
ca. 1454-1455 · Mainz
The Gutenberg Bible is completed in Mainz around 1455, proving that movable metal type can produce a large, authoritative book at a new scale of replication. The event makes technological change feel civilizational: craft, text, commerce, and transmission suddenly reorganize around reproducibility.
Why it matters
The event matters because it marks a turning point in the history of print and in the circulation of knowledge across Europe.
What changed
After Mainz, the printed book is no longer experiment alone, and the balance between manuscript labor and mechanical reproduction begins to shift permanently.
Connected people
Lives that hold the event open
