Valerius Maximus in the context of "Incunabulum"

An incunable or incunabulum (pl.: 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. The specific date is essentially arbitrary, but the number of printed book editions exploded in the following century, so that all incunabula, produced before the printing press became widespread in Europe, are rare, where even some early 16th-century books are relatively common.

They are distinct from manuscripts, which are documents written by hand. Some authorities on the history of printing include block books from the same time period as incunabula, whereas others limit the term to works printed using movable type.
