Note 2296 — Chapter LXII
Reading edition
Petrus de Alliaco, Tractatus de ymagine mundi ... and other treatises by both d’Ailly and Gerson, printed about 1480 (numbered IB.49230 in the British Museum).
In the Elucidarius, cap. 2, d’Ailly cites “Albertus Magnus in suo speculo” two or three times. In the Vigintiloquium de concordantia astronomice veritatis cum theologia, he says, “Unde Albertus Magnus perutiliter etiam tractatum edidit in quo vere astronomie et artis magice libros per eorum principia et fines distinxit.” In the Apologetica defensio astronomice veritatis he cites “Albertus Magnus utique philosophus, astronomus, et theologus” concerning Albumasar’s placing the birth of Christ under the sign Virgo, a passage alluded to in the Speculum, but not, as far as I have noted, in Albert’s other works.
