The images and historiated initials are discussed in Aili and Svanberg (2003), pp. 109–111 and Nordenfalk (1961), pp. 371–393 (the motif description of the historiated initials below are based on these works).The visual programme of the images is most recently discussed by Oen (2019), pp. 186–222 (A 70b is briefly mentioned).

Main text written in dark brown ink, rubrics in red, capitals touched in red or yellow.

The initial is repeated as a plain initial in the text.

(ff. 1r–245v): paragraph or chapter initials in red over 2-3 lines (extending above and below the line). The enclosed space often filled in with yellow. Many of these initials are further elaborated with flourshing and/or pen drawings of human faces, grotesques and animals, e.g. (ff. 7v–10r). The descenders of letters on the bottom line are sometimes extended and flourished, e.g. (f. 3r) and (f. 9v). These are sometimes further elaborated with drawings of figures, e.g. (f. 20v). Some of these features may be later additions.
