Anonymous IV may not be the most reliable source, his treatise dates from at least fifty years after the death of the men mentioned within; Perotin, himself, may never have existed: Anonymous IV is the only mention of the composer. Nonetheless because of their stylistic similrities we accept the works attributed to "Perotin" as coming from the hand of a single composer. In his account, Anonymous IV mentions that Perotin composed two four-voice organa: Viderunt and Sederunt.
Viderunt is an gradual chant for the mass of Christmas Day (at Notre Dame, however, it was reserved for the Mass on January 1). Sederunt is from the gradual chant for St. Stephen's Day (Boxing Day: December 26). Graduals were sung after the epistle (the New Testament reading) and before the Alleluia, basically right before the reading from the Gospel - in this case, the traditional account of the birth of Jesus. Like Alleluias, Graduals were among the most florid and melismatic chants. We can date Perotin's setting based on an edict written by Bishop Odo of Sully - the man in charge of Notre Dame. In the edict, Bishop Odo seeks to put an end to the Feast of Fools, a yearly celebration when the church's rules were stood on their head: asses were led into the pulpit and sausages were consumed on the altar, aong other pernicious acts. In place of the Feast of Fools, the church created the Feast of the Circumcision for January 1. Bishop Odo writes:
"The Gradual [Viderunt omnes] and Alleluia will be sung in two-voice, three-voice, or four-voice organum in silk copes."
Thus it seems likely that Perotin's Viderunt was written for the Feast of the Circumcision in 1198 and his Sederunt in 1199. This luxuriant music would have filled the cathedral during the holiday season.
