A former term for incunable is fifteener, meaning "fifteenth-century edition".
The term ''incunabula'' was first used in the context of printing by the Dutch physician and humanist
Hadrianus Junius
Hadrianus Junius (1511–1575), also known as Adriaen de Jonghe, was a Dutch physician, classical scholar, translator, lexicographer, antiquarian, historiographer, emblematist, school rector, and Latin poet.
He is not to be confused with several ...
(Adriaen de Jonghe, 1511–1575), in a passage in his work ''Batavia'' (written in 1569; published posthumously in 1588). He referred to a period "" ("in the first infancy of the typographic art").
[ Hadrianus Iunius, ''Batavia'', .. ugduni Batavorum ex officina Plantiniana, apud Franciscum Raphelengium, 1588, p. 256 l. 3.] The term has sometimes been incorrectly attributed to
Bernhard von Mallinckrodt
Bernhard von Mallinckrodt (29 November 1591 in Ahlen — 7 March 1664, Burg Ottenstein), dean (''Domdechant'') of Münster Cathedral, was a bibliophile from a noble family of Protestants, who converted to Catholicism.
In 1639 he issued a pamphlet ...
(1591–1664), in his Latin pamphlet ''De ortu ac progressu artis typographicae'' ("On the rise and progress of the typographic art"; 1640), but he was quoting Junius.
The term ''incunabula'' came to denote printed books themselves in the late 17th century. It is not found in English before the mid-19th century.
Junius set an end-date of 1500 to his era of ''incunabula'', which remains the convention in modern bibliographical scholarship.
This convenient but arbitrary end-date for identifying a printed book as an incunable does not reflect changes in the printing process, and many books printed for some years after 1500 are visually indistinguishable from incunables. The term "post-incunable" is now used to refer to books printed after 1500 up to 1520 or 1540, without general agreement. From around this period the dating of any edition becomes easier, as the practice of printing the place and year of publication using a
colophon or on the

Post-incunable
Many incunabula are undated, needing complex bibliographical analysis to place them correctly. The post-incunabula period marks a time of development during which the printed book evolved fully as a mature artefact with a standard format. After about 1540 books tended to conform to a template that included the author, title-page, date, seller, and place of printing. This makes it much easier to identify any particular edition.
As noted above, the ''end date'' for identifying a printed book as an incunable is convenient but was chosen arbitrarily; it does not reflect any notable developments in the printing process around the year 1500. Books printed for a number of years after 1500 continued to look much like incunables, with the notable exception of the small format books printed in
