MSS. Paris:--Bibl. Nat. 14603, fol. 147-216 (sec. xiv): ‘Explicit tractatus venerabilis, theologi Guillelmi Okam de potestate pape.’--Bibl. Mazarine, 3522, f. 104-148 (sec. xiv).
Cf. MS. Rome, Vatican, Bibl. Reg. Sueciae, 79, _De potestate Papae_; and 375, _De potestate utriusque jurisdictionis_.
_De jurisdictione Imperatoris in causis matrimonialibus_, A. D. 1342. _Inc._ ‘Divina providentia disponente.’
Printed at Heidelberg 1598; and in Goldast I, 21. It is of doubtful authenticity; see Riezler, 254.
_De electione Caroli IV_ (written 1347-9). _Inc._ ‘Quia sepe viri ignari.’
See Riezler, p. 271, 303, who refers to Höfler, Aus Avignon, 13.
The following treatises by Ockham are mentioned by Leland, Wadding, and others, but have not been identified.
_De pluralitate formae_, contra Sutton (Leland, Tanner).
_Tractatus incip._: ‘Dominus potest facere omne quod fieri vult non includit contradictionem’:--
seen by Leland in the Franciscan Library, London (Collect. III, 49): Tanner identifies it with _Defensorium Logices_. Perhaps it is the same as _Dialectica Nova_: _inc._ ‘Contradictio in Deo non est.’ (Bale, Pits).
Tanner refers to MSS. Peterhouse 217 (where however no mention of it occurs), and Caius Coll. K. 5 (?), perhaps a mistake for H. 5 = 464, which contains Ockham’s logic.
Vidi etiam tres libros Ochami, quorum primus _De privatione, de materia prima, de forma_ quae est principium, et _De forma artificiali_; secundus vero _De causis materiali, formali, efficiente, finali_; tertius _De mutatione subita_ tractat.
_De perfectione specierum_ (Wadding). _Inc._ ‘Quia Magister.’
_De paupertate Christi et Apostolorum_ (Tritheim, Wadding).
This is probably incorporated in the Dialogus (see Wadding, Ann. Min. VIII, 81-2). Cf. MS. Florence:--Laurentiana, _ex Bibl. S. Crucis_, Plut. xxxi. Sin. Cod. iii (sec. xiv).
_De actibus hierarchicis_, lib. i (Wadding).
Wadding, _Sup._: ‘citat Joan. Picus Mirandulanus in sua Apologia quaest. 1.’
_Errorum quos affinxit papae Johanni_, lib. i (Wadding). _Inc._ ‘Locuti adversum me lingua.’
(Probably identical with one of the extant treatises.)
_Defensorium_ (against the pope); mentioned by Leland, Bale, &c. _Inc._ ‘Omni quippe regno desiderabilis.’
This is the _Defensor pacis_ of Marsilius of Padua.
