The incunabula of the first printed book, like the manuscript books, were still decorated by hand. Because the text in the incunabula was originally without paragraphs, the beginning of the paragraphs or chapters was highlighted in red or blue ink. At the same time, the initials were drawn, additionally decorated in various colors, even gilded. However, a number of incunabula have empty spaces left in place of the first letters, as illumination was a long and expensive process. The commentary on the Song of Songs by the medieval theologian and philosopher Benedictine Honorius Augustodunensis (c. 1080 - c. 1140) is an excellent example of manuscript illustration.
