This manuscript was created in the 13th or 14th century and the hand seems to be Italian. It features a collection of legal texts, focussed on Roman law. They could all be connected to the Corpus Juris Civilis, a legal text compiled by Justinian, traditionally known as Justinian the Great, who the Eastern Roman emperor from 527 to 565. It seems that the texts in this manuscript have been lifted from another manuscript, as some of them start and end imperfectly.

The contents are as follows:

f. 1r-1v: Unidentified legal text, perhaps an Index to Justinian

ff. 2r-7v: De procuratore cogendo judicium suscipere

ff. 8r-13v: Unidentified legal text, beginning tint .ar. ut .FF. deneg. ergo pop

ff. 14r-47v: Index to a legal text, perhaps connected to the previous sections

ff. 48r-51v: Unidentified legal text, perhaps an Index to Justinian, and perhaps the same as ff. 1r-1v

The texts are described separately, under MS 155/ff. 1r-1v; MS 155/ff. 2r-7v; MS 155/ff. 8r-13v; MS 155/ff. 14r-47v; and MS 155/ff. 48r-51v.

The hand seems to change three times, on f. 8r, f. 16r, and 48r, though the hands are similar. MS 155/f. 1 and MS 155/ff. 2r-7v are in a similar hand, which changes during MS 155/ff. 8r-13v. The first part of MS 155/ff. 14r-47v (from f. 14v to f. 16r) is written in a similar hand to that of MS 155/ff. 8r-13v, but the second column of f. 16r switches to a hand that more closely resembles MS 155/ff. 2r-7v.

All the hands are good, the first very small and uniform. There are plain red initials and rubrics throughout. The chapters of the first treatise have been added later in Roman figures.
