Processionale, 1541, probably prepared in
        Gregoriushaus in Emmerich for the Dom in Xanten. Low
        Countries staff notation on ink staves. 
 The second part, starting
        with the rubric Antiphone versiculi et collecte pro lotione
        altarium edis sancti victoris martiris patronis zanthensis ..., is
        not from the original hand.
The rubrics often indicate the persons who are to sing the chants (Tres domini, duo pueri, etc.), and also the places (In processione versus capellam s. Andree etc.).
The manuscript contains several litanies, some of which bear notation.
Fol. 31v: litany without notation 
        Fol. 34r: litany without notation 
Fol. 31: Litany with notation 
        Fol. 44v: Ad aquae aspersionem: ant. Exsurge domine adiuva nos + verse
        Deus auribus 
        Fol. 45r: notated litany (Duo in ecclesia ubi hoc incipient stacio fiet et clausis
        foribus) 
        Fol. 46r: notated litany (Iam litaniae ex breviario) 
        Fol. 49r: notated litany (Hec litania cantabitur in via dum reditur a statione in die
        marci et secunda feria rogationis) 
        Fol. 56r: notated litany Clamemus omnes una voce Domine miserere (In feria
        tercia cantabitur hec dum itur versus montem (?) iuxta hospitale incipietur) 
        Fol. 57r: notated litany Aufer a nobis domine iniquitates nostras (Hec letania
        incipietur circa mediam viam usque montem et cum ea intrabitur in ecclesiam in
        vorsteberge) 
        Fol. 58v: notated litany Ardua spes (Hec cantabitur dum reditur de monte
        dictis vigiliis). NB: on f. 60v Martinus, Lebuinus
        and Willibrord are mentioned. 
        Fol. 62v: notated litany (Hec cantabitur feria quarta dum reditur a statione et ante
