Processu temporis magister Johannes Theutunicus accepit constitutiones concilii Innocentii et quasdam decretales quas  Innocentius sexto anno sui regiminis usque ad concilium fecit in sex annis sui regiminis usque ad concilium et compillavit et glosavit, et vocatur quartus liber decretalium.  Set quia dominus Innocentius noluit illam compilationem actenticare (approbare V), ira succensus recessit de curia. Vatican, Borghese lat. 45, fol. 23r-23v (V) and Breslau, Universitätsbibliothek 1.Q.102, fol. 201v-202r (B)
