The manuscript is written by two 15th-century hands (changing after folio 30, vi. 487). Folio 70 (an inserted leaf) repeats xiv. 93-142, already written on folio 69. The first part is of the Ξ group (cf. `Handschriftliche Grundlagen des Juvenaltextes`); the second part, although it has the Ξ feature of xv being placed after xvi, appears to have a Ψ text.

The first part is written in a neo-Caroline hand, closely imitating the script of the 11th and 12th centuries (indeed it has been ascribed to that period by many, but it has the significant pointer of dotted i`s, cf. L Laurand in ‘Revue des études latines’, xi, 11-12); the second part is in a round humanistic hand. Space has been left for a title and for initials to each satire, but these have not been added. There are interlinear and marginal glosses on folios 1-25 (as far as vi. 236), and occasionally thereafter. On folio 81 verso is written the couplet `Vt imbre tellus: sic riganda mens meus. /Vt illa fruges, hec bona consilia efferat`, then various pen-trials, then `Al M[?fico] Ill[?re] Sig:[?r] and Prone mio /Obb[?m] il sⁿ Pietro Vrbani`, in a 16th-century hand. The numbers 52 and 120 occur on the upper and lower pastedowns respectively.
