The text is written in two different Italian scripts of the early or mid twelfth century. The first hand ceases after the first three letters of f.84r (the - dam of quodam in Liber de Vita Christiana IV.44). The first line, after -dam, and the next three lines of f.84r are blank. The second hand begins on the fourth line at the start of Liber de Vita Christiana IV.45 with ‘Filius Romanum ecclesiam’. The second hand is smaller and rounder, probably later than the first, which is more clear and consistent through the first half of the text. The layout and structure of the text, including patterns of the rubric, remains the same throughout despite this change.
