Books printed before 1500, within the first fifty years of Gutenberg’s invention of printing with metal movable type, are called incunabula (in-kyə-ˈna-byə-lə), from the Latin word meaning “a cradle.” These are books from the infancy of printing. The great majority of these works were religious works, including Bibles. Several excellent incunabula are on display in the Dunham Bible Museum.
