In Cortona 35, 15th century, fol. 203, the _Didascalicon_ in six books is first followed by a brief passage, _Divisio philosophie continentium_, which is perhaps simply the fourteenth chapter of the sixth book as printed in Migne, and then at fol. 224 by the passage concerning magic and its subdivisions. The account of magic also occurs in MSS which do not contain the _Didascalicon_, for instance, Vatic. Palat. Lat. 841, 13th century, fol. 139r, “Magice artis quinque sunt species....” [20] “Malefici sunt qui per incantationes daemonicas sive ligaturas vel alia quaecunque exsecrabilia remediorum genera cooperatione daemonum atque instructu nefanda perficiunt.” [21] “Praestigia sunt quando per phantasticas illusiones circa rerum immutationem sensibus humanis arte daemoniaca illuditur.” [22] Migne, PL 177, 13-164, “Hugo Raynero suo salutem. Desiderii tui petitionibus, charissime, satisfacere cupiens....” [23] I, 45. “De incertis per experimenta loquitur, sed experimentum est fallax, ideo saepe fallitur. Sed hoc religioso non expedit ut alia quam vera loquatur.” [24] II, prologus. “Ferae appellantur eo quod naturali utantur libertate et desiderio suo ferantur. Sunt enim liberae eorum voluntates et huc atque illuc vagantur et quo animus duxerit eo feruntur.” [25] _Etymologiarum_, XII, ii, 2. APPENDIX I SOME MANUSCRIPTS OF DE BESTIIS ET ALIIS REBUS OR THE GILDED DOVE The _De bestiis et aliis rebus_ or _Columba deargentata_ appears with other opuscula of Hugh of St. Victor or Hugh of Folieto in Vendôme 156, 12th century, fol. 1v--, “Libellus cuiusdam ad fratrem Rainerum corde benignum qui Columba deargentata inscribitur. Desiderii tui, karissime, petitionibus satisfacere....” Dijon anciens fonds 225, 12th century, fols. 92v-98, “Prologus Hugonis prioris in librum de tribus columbis. Desiderii tui, karissime, petitionibus satisfacere....” Cambridge University has several copies, most of which seem to differ from the printed edition and from one another. CUL 1574, 15th century, Liber de bestiis et aliis rebus; the arrangement is said to be very different from that in Migne. CUL 1823, 12th century, “Liber bestiarum”; similar in text to the foregoing, but with a different order of chapters, “and there are both large omissions and insertions.” The numerous figures of animals in outline “are remarkable for their finish and vigor.” CUL 2040, late 13th century, fols. 50-93, “De natura animantium”; said to be “substantially the same as that of Hugo de S. Victore; the arrangement, however, is very irregular.” CU Sidney Sussex 100, 13th century, James’s description (pp. 115-7) shows it to be our treatise; for its fine miniatures see James (1895) pp. 117-20. A few other MSS (doubtless the list can be greatly augmented) are:
