In the history of printing, an incunable or incunabulum (plural incunables or incunabula, respectively), is a book, pamphlet, or broadside that was printed in the earliest stages of printing in Europe, up to the year 1500. Incunabula were produced before the printing press became widespread on the continent and are distinct from manuscripts, which are documents written by hand. Some authorities include block books from the same time period as incunabula, whereas others limit the term to works printed using movable type.
