Liturgical chant pages used as binding for another work with a partially legible German title. Chant appears upside-down on the front cover; the first line, "...nt ga est flos filius" matches the text of Stirps Jesse. It is followed by a doxology (Gloria Patri) including some abbreviated text, and then the text of Veni in hortum meum soror, associated with Matins for the Assumption of Mary. The back cover has an upside-down portion, "dominus in suis virtutibus vincula manuum relaxavit suamque famulam de morte," which is associated with Lauds for the feast of St. Margaret of Antioch. The remainder contains notated chant for Vespers for the feast of St. Michael and All Angels (domine deus noster accipere librum et aperire signacula ejus), and from Matins for the same feast, with the text from Angelorum regi deo jubilemus pariter, then from Introibo in domum tuam domine, and finally the beginning of Stetit angelus juxta aram templi.
