Translated from the Arabic by Adelard of Bath, probably around 1120. This translation does not include Abū Jaʿfar Aḥmad ibn Yūsuf’s commentary and breaks off after v. 39 in all copies.

Note Besides the two manuscripts listed below, this version survives in about 20 copies as part of the so-called ‘threefold version’ described under Plato of Tivoli’s translation of Abuiafar Hamet filius Joseph’s commentary on the Centiloquium (see C.3.1.1, Note 3). Verba 1-25 also occur together with the ‘Mundanorum’ version of Abuiafar’s commentary (C.3.1.3) in MS Leipzig, UB, 1463, and the first verbum only, also with ‘Mundanorum’, in MS Berlin, SBPK, lat. fol. 246.

Text ‘(London, BL, Sloane 2030) [1] Doctrina stellarum ex te et illis. Nec est docti in ea ut prophere (!) formam actus individualis sicut nec sententis ut capiat formam sensiti individualem… [2] Cum quesierit electionem meliorem, non est inter eum et connaturalem diversitas. [3] Connaturalis in re est cui invenitur dux huius rei potens in nativitate eius. [4] Anima connaturalis iudicabit super elthenias, id est secundas stellarum… (87v) [5] V. Iam potest astrologus supra removendos multos actus stellarum… [6] VI. Proderit autem cum electione cum fuerit hora addens supra incrementum… [7] Non accedat ad iudicium supra complexiones stellarum… [8] VIII. Anima sapiens actum stellarum adiuvat <sicut> seminator potens… [9] Forme que in mundo composito sunt formis circularibus obediunt… [10] Subserviant tibi infelicitates in electionibus, sicut quod facit medicus peritus cum quantitate sufficienti — [39] Mala habitudo undecimi et domini eius in statutione regis, dux supra eventus principis et censum eius infortunii. Similiterque mala habitude secondi dux supra parvitatem lucri agricolarum suorum cum eo.’
