Digby 228, 14th century, fol. 76-, no author is named in the text itself of the Speculum but in the upper margin of this page a hand of the same century has written the following note: “Tractatus magistri Philippi cancellarii Parisiensis de libris astronomie qui tenendi sunt secundum integritatem fidei catholice et qui non.” This MS seems to give a more correct text than any of the three following other MSS in the Bodleian.
Ashmole 345, later 14th century (the name, “Kenelme Digby,” is written at the top of the first page of the MS), fols. 14v-21, Tractatus in quo corriguntur errores quorundam astrologorum et philosophorum fidei catholicae repugnantes, “Occasione quorundam librorum apud quos non est radix scientie ... / ... sed quod ambo inveniuntur ab eodem creata. Explicit.” Although it opens as usual, it omits much of the earlier chapters and bibliography of the Speculum. No author seems to be named.
Digby 81, on paper, fols. 102-18, “Explicit iste tractatus quem composuit Albertus frater predicator.” But a hand of the 17th century adds the note, “Albertus non fuit author huius libri sed Philippus cancellarius Parisiensis, ut ex vetustissimo exemplari manuscripto manifestum est,” which I presume is a reference to the note to that effect in Digby 228. As a table of contents for this portion of the MS at fol. 101r shows, this “Albertus de scientiis licitis et illicitis” was once followed by “Cosmographia Rogeri Bacon”; but it will be noted that although the 17th century hand questions Albert’s authorship, its writer was not moved to ascribe the Speculum to Bacon.
Canon. Misc. 517, 15th century, fols. 52v-59v, “Incipit speculum alberti ... / ... finis Spectubili Alberti.” Written in a print-like hand which is prettier than Digby 228, but the text nevertheless contains a good many slips, as in the omission of words from the Incipits in the bibliographies of deserving and illicit books. Also it has 19 chapters instead of the usual 17, as in Digby 228 and the printed text.
The following MSS I have not examined but list according to the various catalogues:
Arsenal 387, 13th century, fols. 16-31. Fols. 15-34 are now missing but in the 16th century Claude de Grandrue gave the description: “Liber Alberti magni de nominibus librorum astronomie tam demonstrativum quam judicialium, ut sciatur qui libri sunt contra fidem et qui non.” The correspondence of this wording with BN 7408 is perhaps worth noting.
Brussels, Library of Dukes of Burgundy, 936, anno 1418, Alberti Maqui Speculum astronomiae; 1030, 15th century, Alberti Magni Speculum; 1466, 15th century, an abridgement of the Speculum.
Florence, Ashburnham 136, early 15th century, fols. 178-83, Speculum Alberti Magni.
Catania 87, 15th century, #13, Albertus Magnus, Summa librorum astronomiae.
S. Marco XI-71, 16th century, 19 fols., Alberti Magni astronomiae speculum. Valentinelli remarks, “Opus Rogero Baconi male tributum, recte sub Alberti Magni nomine pluries editum est.”
