It occurs at fols. 59-88 of Canon. Misc. 555, immediately after the Liber particularis, and is found in other MSS.
Commentary on The Sphere of Sacrobosco.
Eximii atque excellentissimi physicorum motuum cursusque siderei indagatoris Michaelis Scoti super auctorem sperae cum questionibus diligenter emendatis incipit expositio confecta Illustrissimi Imperatoris Dn̄i D. Fedrici precibus, Bologna, 1495. I have also used an edition of 1518, and there are others.
Liber lumen luminum.
Riccardian 119, fols. 35v-37r, “Incipit liber luminis luminum translatus a magistro michahele scoto philosopho.”
Printed by Brown (1897), Appendix III, pp. 240-68.
I presume it is the same as the Lumen luminum ascribed to Rasis in BN 6517 and 7156—see Berthelot (1893), I, 68—but I have not compared them.
In the same Riccard. 119 at fol. 166r is a Liber lumen luminum ascribed to Brother Elias, general of the Franciscans. “Incipit liber alchimicalis quem frater helya edidit apud fredericum Imperatorem. Liber lumen luminum translatus de sarraceno ac arabico in latinum a fratre cypriano ac compositus in latinum a generali fratrum minorum super alchimicis. Incipit liber qui lumen luminum dicitur ex libris medicorum et experimentis et philosophorum et disciplinarum ex(t)ranearum.”
