Initial B with the Holy Trinity
The manuscript can be dated to before 1285.
This initial begins the Introit for the feast of the Holy Trinity, "Benedicta sit sancta trinitas ..." (Blessed is the Holy Trinity). The liturgy of this missal follows the Dominican liturgy established by Humbert of Romans, Master General of the Dominican Order (1254-1263). This manuscript is unusual because it contains both the sung and spoken parts of the mass. More often, the sung parts of the Mass were found in separate books called graduals. This feature and the small size of the manuscript suggest that it was for the personal use of a Dominican friar.
