Balbi, Catholicon, 1460 (1r)

One of the first books to be printed, the 1460 Catholicon continues to be surrounded by uncertainty about exactly who made it and what processes were used. Although it was once assumed that Gutenberg printed the book, that is now doubted. And recent theory is that the book was not printed with individual pieces of movable type, but with cast two-line slugs of type, thus explaining the near exact later impressions printed in 1469 and 1472.

Jacobus, Golden Legend, 1472 (fol. 2r)

The text of this German edition of The Golden Legend of Saints starts off with an equivalent to "incipit": "Hie hebt sich an das Sumer Teil der Heyligen Leben..." ("Here begins the Summer Part of the Holy Lives..."). A hand-colored portrait of Jacobus writing his work follows.

Jacobus, Golden Legend, 1472 (fol. 5r)

The start of the life of Saint Mary of Egypt is marked off by a hand-colored woodcut illustrating her life. Like other books from the earliest years of printing, this does not use many of the printed features that become standard, including headlines, paragraph breaks, signature marks, or catchwords.

Rinuccio, Aesop, 1521 (sig. c7r)

A unique feature of this text is how the morals are isolated in the margins next to their respective fables. The use of the manicules and banners serves to emphasize the lofty values they impart.

Sacrobosco, Noviciis adolescentibus, 1485 ([1]1r)

As title pages developed in form sometimes blank leaves or pages preceded them. In this case, as you can see from the bleed-through, a woodcut on the verso of the first leaf faces the inicipt and text on the second leaf.

Sacrobosco, Noviciis adolescentibus, 1485 ([1]1v)

This woodcut---one of the standard ones accompanying Sacrobosco's astronomical textbook---is in this edition facing the beginning of the text and the incipit.

Sacrobosco, Noviciis adolescentibus, 1485 ([1]2r)

Sacrobosco's works were some of the most influential astronomical texts of the middle ages. It was frequently collected with works from Regiomantus and Peurbach as a textbook on the subject. The incipit (even though it's not preceded by the phrase) provides the title under which this collection is cataloged, rather than the more commonly used De sphaera mundi.
