Invention — printing
Johannes Gutenberg's workshop in Mainz combined cast, reusable metal type with an oil-based ink and a screw press adapted from winemaking, producing a machine that could turn out identical pages in quantity. His 42-line Bible of about 1455 is the first substantial European book printed from movable type. Within fifty years presses were running in most major European towns, and the flood of cheap printed matter underpinned the Reformation, the Scientific Revolution and the standardisation of national languages.
