Translated by Hugo Sanctelliensis and dedicated to Bishop Michael of Tarazona (1119-1151). The translation is not dated, but a ‘magister Hugo’ appears as a witness in charters issued by Michael of Tarazona in 1145 and 1147 (Santoyo, 342).

Text ‘(Madrid, BN, 10009) [translator’s preface] De hiis que ad iudiciorum veritatem attiinent (!) cum in illis totus astronomie consistat effectus secundum Arabice secte verissimam inquisitionem — qui pocius gaudeat librorum numero quam eorum delectetur artificio. (85rb) [1] Astrorum scientia de te et de illis. Hoc in sermone ‘de te et de illis’ videtur velle Ptholomeus duplicem esse astrorum scientiam et gemino calle terminari… [comm.] Deinceps quoque ad significationem stellarum signorum et ad eos qui eiusdem sunt ca(85va)paces… (86rb) [2] Quociens optima requiritur electio, ipsius ad naturalem nulla est differencia. [comm.] Estimant quidam posteriorum Ptholomeum hoc in loco eam electionem velle dicere quam… (86va) [3] Naturalis in re qualibet vis satis congrue appellatur in cuius nativitate eius rei dux atque minister potens invenitur et fortis. [comm.] Reffert nobis Ptholomeus in sermone 86 stellas omnem administrare creaturam et voluntatis… [4] Anima naturalis per stellarum secundas, id est adiuncta diiudicans certiorem numpciat effectum quam plerique qui de ipsis stellis diiudicant. (86vb) [comm.] Quomodo anima sit naturalis supra dictum fore existimo. Sunt igitur secunde astrorum earum renovationes… [5] Potest astrologus multos astrorum pervertere actiones si naturaliter de horum signis vel effectu peritus extiterit… [comm.] Quamvis una eademque sit actio per diversitatem subiectorum recipientium eam, necesse est variari… (87ra) [6] Prodest semper electio quociens hore potencia utriusque rectoris differenciam excedit… [comm.] Na[m]scentis ducatus et hore potencia quando in bono conveniunt nati profectus exagerant… (87rb) [7] Non pervenit ad iudicium secundum astrorum comixtiones nisi morum consuetudines et comixtiones naturales prudenter congnoscit (!). [comm.] Stellarum commixtionem id intelligere voluit quod ad earum naturam spectat attinet… (87va) [8] Anima sapiens et discreta circularem actionem iuvat, quemadmodum agricola arando et purgando nature subvenit. [comm.] Per hoc quod dicit: anima scilicet sapiens, eam vult intelligere que circuli vires comprehendit arte… [9] Forme huius mundi formis circularibus obediunt easque secuntur. Unde qui prestigiorum scientia… (87vb) [comm.] Huius sermonis intelligenciam ex multiplici prestigiorum archano et ex eorum qui se hoc scire profitentur institutis… (88ra) [10] Infortunia sub omni electione notanda sunt aque observanda, sicut medicorum prudentissimi toxica et venenifera quantum res expostulat exsecuntur. [comm.] Quorumdam astrologorum inprudencia cuiuslibet electionis ducem felicem statuunt atque fortunatum ipsumque corroborant… (96ra) [51] Locus Lune in nativitate est ipsius orientis in circulo gradus sub conceptione, et quem sub conceptione possidet est ipsius natalis orientis gradus. [comm.] Astrologorum omnium et qui nature secreta rimantur generalis est sentencia varios esse status fetuum in materno utero… (97va) [60] Certissimi egrotantium dies cretici sunt hore in quibus apparet languentis mutatio ad bonum sive ad malum infra breve tempus, hoc est situs Lune in angulis… (97vb) [comm.] Hoc in sermone ostendit nobis Ptholomeus creticorum dierum causam et que sit inter ipsos distancia… (105ra) [99] Navicula et comete non de stellis sed de secundis sunt astrorum. [comm.] In supradictis dictum existimo secundas astrorum eorumdem esse in ethere renovationes… [100] Iacula vaporum indicant siccitatem, ex eadem vero parte ventos ibidem nunciant futuros… (105va) [comm.] Aristotiles in libro quem de superioribus composuit signis manifeste affirmat siccos vapores qui ad ethera perveniunt in iacula que superius — et finitimas in manu forti atque violenta agregavit regiones. Manifesto tandem experimento cognovit Egiptus quecumque hoc in loco recensuit Ptholomeus. [finis] Hec sunt que de eiusmodi verborum explanatione ydonea cognoscens a preceptorum via nullatenus arbitror dissentire. Quare et his qui se tanti muneris dignos exhibent diligenter conferenda, et ab his quibus pocior est librorum numerus quam sensus avida manu subtrahenda.’
