The smaller of these divisions containing that portion of the liturgy which is said in every Mass, the "Ordo Missae" with the prefaces and the Canon, is placed, probably with a view to the more convenient opening of the book, near the centre of the volume immediately before the proper Mass for Easter Sunday.
This is supplemented by a certain number of votive Masses, among the rest Masses for the dead, and a collection of sets of collects, secrets and post-communions for special occasions.
Here also are inserted certain benedictions and other miscellaneous matter, while appendixes of varying bulk supply a number of Masses conceded for use in certain localities or in certain religious orders, and arranged according to the order of the calendar.
Certainly it may be affirmed with confidence that what was afterwards known as the "Missale plenum", a book like our present Missal, containing all the Epistles, Gospels, and the choral antiphons as well as the Mass prayers, did not come into existence before the year 900. Adalbert Ebner, who spent immense labour in examining the liturgical manuscripts of the libraries of Italy, reports that the earliest example known to him was one of the tenth century in the Ambrosian Library at Milan ; but although such books are of more frequent occurrence from the eleventh century onwards, the majority of the Mass-books met with at this period have still only an imperfect claim to be regarded as "Missalia plena".
We find instead a great variety of transition forms belonging to the eleventh, twelfth, and thirteenth centuries which may be referred in particular to two distinct types.
In the first place the sacramentary, lectionary, and antiphonary were sometimes simply bound up together in one volume as a matter of convenience.
