Manuscript, probably written in Italy, containing a complete copy of 'De Trinitate' of St Augustine, as well as a work entitled 'Expositio fidei Catholicae'.

The manuscript is probably of the 12th century, and has been dated as such by the summary catalogue, Römer, and Borland. In private correspondence with the National Library of Scotland Michael Gullick suggests that this manuscript may be of Italian origin from the 11th century. Heinrich Schenkl suggests that the work can be dated to the end of the 11th century, but also that it may be a forgery of the 15th century due to the condition of the vellum.

The work appears to be written by one hand in a protogothic book hand with 31 lines to a page.

The contents are as follows:

St Augustine of Hippo, 'De Trinitate'. Each Book opens with a table of contents. Folios 1r-210r.

'Expositio fidei Catholicae'. Incipit: 'Quicumque vult salvus esse ante omnia opus est ut teneat catholicam fidem.' Folios 210r-215r.

On folio 215r there are 8 lines of philosophical syllogisms.

On folio 215v there is a passage on hospitality in monasteries.

Folio 215 is a palimpsest. There is a partially erased text of Luke, chapter 18, on the verso side. This was possibly part of a rejected faulty copy of a leaf of a missal or breviary rather than of a Bible or New Testament.

There are marginal annotations visible throughout the manuscript. These are scribal and provide additions or amendments to the text.

Incipits and explicits are given in red. At the beginning of each book are red and gold decorated initials which are ornamented with strapwork or floriated. Each chapter begins with a large red initial, and smaller capitals are stroked throughout in yellow. Guide letters are occasionally visible in the margins for the decorated initials.

Hard point lining and ruling is visible on each folio recto and verso. Pricking is visbile for both the horizontal and vertical lines.

Catchwords are visible on the following folios: 16v (cropped), 88v, 96v (cropped), 212v (cropped).

Contemporary repairs to the vellum can be seen on folios 210 and 211.
