Compilatio libri iudicialis Ptholomei in nativitatibus secundum ordinem domorum


‘(Gloucester, CL, 15) Compilatio libri iudicialis Ptholomei in nativitatibus secundum ordinem domorum procedens… [end of title difficult to read]. Expedita autem theorica nativitatum secundum canones Alchabitii vel alterius introductoris… Ait itaque Ptholomeus tractato (!) 3°, capitulo 9°: Quando aliquod luminarium fuerit in aliquo angulorum figure precise — similiter si dominus prime domus radicis nativitatis fuerit in decima revolutionis, idem iudicabis …us (?) vide in parte et capitulo eiusdem … (?).’


A recasting of Ptolemy’s doctrines on nativities (Quadripartitum III-IV) following the order of the 12 houses with a last section devoted to the revolutions of nativities. The main source is the Quadripartitum, but the author also refers to the Centiloquium on several occasions, as well as to other authors (Haly Abenragel and Leopold of Austria).


Written by an anonymous scholar who likewise summarised and paraphrased a large number of astrological texts in what appears to be the autograph MS. One section in the MS is dated 1507 and this is likely to be the approximate date of the whole MS.
