The manuscript is a 14th century Collectarium. The collectarium is a book that contains Collects, which are short general prayers of a particular structure used in Christian liturgy. This version originated in Italy; a Perugian provenance is clearly indicated, with Sienese connections. It is also specifically Cistercian.

The Kalendar starts on f.1r.

In the Kalendar, the distinctively Cistercian marks are: 10 January: Viliemi [i.e.Guillelmi] (Bishop) C, xii lc.; 11 January: Commemoratio Episcoporum et Abbatum (Commemoration of Bishops and Abbots, in red); 16 February: Juliana (Virgin Martyr), xii lc. (in red); 20 April: Robert C, xii lc. (in red); 30 April: Petri (martyr), xii lc.; 8 May: Petri (Bishop), xii lc. (in red); 20 May: Commemoratio omnium defunctorum ordinis nostri (commemoration of the masses for all the dead of our order) [inserted]; 13 July: Obiit Reverendus pater bone memorie dominus Johannes et Sancte Rufine Episcopus et fundator (in red); 19 July: Margarete (Virgin Martyr) [inserted] (in red); 11 August: Festum Sancte Corone Domini (Feast of the Holy Crown) xii lc.; 20 August: Bernard (Abbot), xii lc.

All these are also in the Sanctorale.

Other distinctive names are: 29 January: Constantius (Bishop of Perugia, martyr), xii lc. (in red); 1 March: the Translation feast of Herculane (Bishop of Perugia, martyr), xii lc.

[inserted] (in red); 3 December: Galganus of Siena C, xii lc. (in red) . None of these last appeared in the original Sanctorale. Saint Yvo, Saint Anne and Saint Juliana are inserted in the Commune Sanctorum, and Capitula and Collects for Saint Malachy, Saint Galganus, and Saint Juliana are added at the end.

The Proprium de Tempore starts on f.7r. This section contains liturgical texts for days that have special Masses or Offices (e.g. prayers, lessons).

The Proprium Sanctorum starts on f.52r. This section contains the Offices of the Saints. In this version, Collects for Saint Mary Magdalene and Saint Anne are added.

The Commune Sanctorum starts on f.86r. The Commune Sanctorum, or Common of Saints, is part of the liturgy that consists of texts concerned with categories of saints, such as apostles or martyrs.

The In Dedicatione Ecclesie (Dedication of a Church) starts on f.95r.

The Orationes votivae (vows) start on f.96r. In this version, feminine forms are added to some of these.

The Litany starts on f.97v. The litany is a series of petitions for use in church services or processions, usually involving recitation by clergy and response by others. This Litany is not very distinctively Cistercian. Saint Anastasia and Saint Benedict are doubly honoured. The Suffrages are individual and masculine, Ut spiritum famuli tui in sinu Abrahe recipi jubeas, etc.

The Service of the Dead starts on f.100r.

The Orationes votivae continue on f.106r.

The Gospel for the Sermo Domini Ceremony of Maundy Thursday starts on f.109r.

There is one fly-leaf at the start and one at the end. Both these, and the back of the front and back boards feature a choral composition.

A good Italian Gothic script with rubrics and red, blue, and purple filigree initials. The initial at the beginning, probably an illuminated one, has been removed, but part of the border remains. There are certain additions at the end by later hands.
