Work B.6

De iudiciis partium


‘(Florence, BNC, II.III.214) Incipit liber de iudiciis partium Ptolomei. Et primo de parte fortune, hic accipitur in die a Sole in Lunam, in nocte e converso et proicitur ab ascendente. Quoniam et in primo libro partium terminos et loca posuimus, iudicia sub earundem munstrare (!) curavimus. Pars fortune et eius dominus corpus et que ad corpus attinent significat — aut eius domini hiis XII mensibus mutatur.’


Interpretation of the position of the part of fortune and of the parts associated to the twelve houses in each of the twelve houses (on which see Albumasar, Introductorius maius, VIII.4).


As already noted by Pingree (‘Māshā’allāh: Greek, Pahlavī…’, 125), this text is identical in wording to a chapter of Messahallah’s De nativitatibus I (e.g. Oxford, BL, Savile 15, s. XV, f. 181ra-182rb: ‘Pars fortune eiusque dominus. Corpus et que ad corpus attinent significavit…’), a translation of Māshā’allāh’s Kitāb al-mawālīd al-kabīr made by Hugo Sanctelliensis before 1151. The attribution to Ptolemy might simply result from the fact that in most MSS, including the two earliest ones (s. XIII2), the text follows Ptolemy’s Quadripartitum (tr. Plato of Tivoli) and Pseudo-Ptolemy’s Liber proiectionis radiorum stellarum (Madrid, BN, 10063; Munich, BSB, Clm 3857; Vatican, BAV, Barb. lat. 328; idem in Vatican, BAV, Ottob. lat. 1552, but without the Quadripartitum), and it is even considered to be the last chapter of the Quadripartitum in Munich, BSB, Clm 3857.
