Commentary on the Centiloquium
‘(Cracow, BJ, 1857) [preface] Gloriosus reor zonas intueri mundiales a limitibus altis… (72) [comm.] In nomine Ihesu. Circa prohemium centum verborum dum dicit: Mundanorum mutacio etc. Albertus Magnus in libro de fato talem mutacionem dicit… (75) [text] Mundanorum ad hoc vel ad illud mutacio corporum celestium mutatione — et ego Deum precor ut te dirigat.’
A commentary or university lectures on the Centiloquium mainly in Plato of Tivoli’s translation (B.1.2) but also in the ‘Mundanorum’ version (B.1.4).
Composed by Andreas Grzymala of Poznań, professor at the University of Cracow from c. 1447 (when he received his Master of Arts) to his death in 1466. He taught astronomy for a few years only, until he became professor of poetry and rhetoric c. 1450. He produced his Canones tabularum resolutarum in or soon after 1448 and it is likely that the commentary on the Centiloquium dates from around the same time. Andreas Grzymala signed his work in the initials of the first words of the preface (‘Gloriosus reor zonas intueri mundiales a limitibus altis…’), as was common among Cracow authors of the 15th c. The exact nature of this commentary is however unclear. Rosińska speaks of university lectures, which is entirely plausible. In the only known MS (Cracow, BJ, 1857), this commentary consists of a preface (p. 71) and a substantial beginning (pp. 72-74), then of marginal comments giving the opinions of other scholars, but these comments stop after v. 20 (p. 85) and it is difficult to say whether Andreas Grzymala’s commentary was left unfinished or whether the scribe of the MS was responsible for this state of affairs. For more details, see the entry of the MS in question.
