Cf. _Dialogus_, Pars III, Tract. v. _Tractatus oquā_ (sic) _de potestate imperiali._ _Inc._ ‘Inferius describuntur allegaciones per plures magistros in sacra pagina approbate per quas ostenditur evidenter quod processus factus et sentencia lata in frankfort per dominum lodowicum quartum dei gracia Romanorum imperatorem.’ The decree of Louis referred to is dated Aug. 6, 1338[1471]. MS. Rome:--Bibl. Apostol. Vaticana, Codd. Palat. Latin. No. 679. Pars I, fol. 117 (sec. xv). Cf. Boehmer, Fontes rerum Germanicarum, Vol. IV, p. 592, ‘ex libro Nicolai Minoritae de controversia paupertatis Christi 1324-1338.’ _Inc._ ‘Subsequenter ponuntur articuli et describunter de juribus imperii.’ _Octo questiones super potestate ac dignitate papali_, or _De potestate pontificum et imperatorum_ (written between 1339 and 1342). _Inc._ ‘Sanctum canibus nullatenus.’ _Inc. quest._ 1. ‘Primo igitur queritur utrum potestas spiritualis et laicalis suprema.’ 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. I. _Philosophical._ _De pluralitate formae_, contra Sutton (Leland, Tanner). _De invisibilibus_ (Leland). _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). _Comment. in Metaphysicam._ 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. Leland adds: 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. [Cf. _Quaestiones in lib. Physic_?] _De perfectione specierum_ (Wadding). _Inc._ ‘Quia Magister.’ II. _Political._ _De paupertate Christi et Apostolorum_ (Tritheim, Wadding).
