| B-LVap 20 |
Notated Missal, late 12th or early 13th century. Low Countries notation (with angular clivis), staves partly red, partly in ink. Sometimes a more lorraine-like notation occurs (e.g. on fol. 31r bottom margin, f. 207). Prefaces etc. are added in a younger hand using square notation on red staves.
Borremans (pp. 9-10, fig. 9, 13) says that the corrections and additions betray that the ms has been used in a premonstratensian abbey and that its liturgy is arranged according to the premonstratensian use, though it is not from premonstratensian origin. By Van Waefelghem (p. 251, nr. 557, and p. 365) it is attributed to the Sulpitiuskerk in Diest; this attribution is adopted by N.J. Weyns: Le missel Prémontré, in: Analecta Praemonstratensia 43 (1967), p. 204 (nr. 12). There is, however, nothing in the manuscript that refers to Diest. On the contrary, on fol. 104v is a Missa de sancto Gummaro, pointing towards Lier. This mass (texts only) is added in a 15th century cursive script. It contains a sequentia for Gummarus: In excelso triumphanti.
Neither the Sanctorale (Preiectus, Octava Agnetis, fol. 165r) nor the litany (Servatius, Trudo; fol. 67 ?) give decisive details about the origin of the manuscript.
Between fols. 114 and 115 is a small loose fragment with staffless 11th century lorraine neumes.
- Fols. 1-102r: Temporale
- Younger additions: Fol. 104v: Missa de sancto Gummaro; fol. 105r: preface tones,
canon, pater noster (square notation on red staves); fols. 117-131: part of a
missal, not noted, 15th (?) century
- Fols. 132r ff.: Dominicae per annum; Sanctorale (original hand)
