A commentary on Quadripartitum I-II in the translation of Egidius de Tebaldis (A.2.5), written in Cracow in 1463, as it appears in an excursus on the great conjunctions in II.4: ‘ad annum equidem Christi 1463 currentem… anni illius ad meridianum inclite civitatis Crac<oviensis>…’ (MS Memmingen, SB, 2º 2,34, f. 147ra – the date 1463 is given several times as the present year in the same chapter, f. 147ra-148rb). In II.11, the author gives the precessional increment for 1463 as 18°41′ and states that this makes a difference of two decans in longitude since Ptolemy’s epoch (‘Nam ad loca stellarum per Tolomeum verificata pro anno nostro 1462 completo adduntur 18 gradus 41 minuta, que faciunt fere duas facies’, f. 159rb). A similar statement is found in a note which accompanies Petrus Gaszowiec’s Tabula de naturis particularibus signorum et facierum (C.2.7) in three of its five manuscripts: ‘Item, octava spera tempore Ptolomei huc usque mota est 19 gradibus et quasi per duas facies recessit octava spera a nona’ (Munich, BSB, Clm 51; Paris, BnF, lat. 7350; and Vatican, BAV, Pal. lat. 1439). Considering that the Tabula deals with the same chapter II.11 and was also made in Cracow in 1463, it is tempting to ascribe the present commentary to Petrus Gaszowiec.

Note The commentary closes with, or is followed by an appendix, which turns out to be a Haly Abenrudian’s addition to Quadripartitum II.13, i.e. Hermes’s Liber de accidentibus (see C.2.2 under Note 4).

Text ‘(Memmingen, SB, 2º 2,34) (125ra) [preface] Inter utiliores vias quas in editionibus viderimus sapientum de astrorum doctrinantium influxibus (?) processus quem gloriosus astronomorum prime signifer Ptholomeus Saludranus in libro quartuo (!) partium ordinavit — et ingeniorum aviditati. (125ra-141rb) [book i] Due sunt scientie ad pronosticationes complementum requesite secundum quod duobus modis — in aliis autem locis debiles sunt et vim non habent. (141rb-162rb) [book ii] Liber secundus de revolutionibus annorum. Capitulum primum de divisione universali huius artis. Iam sufficienter locuti sumus de universalibus principiis et regulis introductoriis huius artis in libro primo, convenit ut in isto secundo loquamus de modo applicationis predictarum regularum — ad varietatem colorum prout sepe dictum est. Et hec sunt in summa sententie domini Ptholomei de rebus et accidentibus universalibus ex secundo eius libro collecte. (162rb-163vb) [appendix] Verum quia dominus Hali in fine capituli addit certa verba utilia domini Hermetis in libro suo de accidentibus, scripta et michi visum fuerit (?) utile eadem hic subscribere. Dixit Hermes: Ordina significatores primo etc. etc. Primo fortiorem postmodum debiliorem — Hic enim adiunximus multa de dictis Hermetis de quibus proficies si Deus voluerit. Explicit secundus Quadripartiti Pthololomei.’
