Note 203 — Chapter XXXVIII
Reading edition
Ed. Ludwig Baur, in Beiträge, IV, 2-3, Münster, 1903, pp. 1-144 text; pp. 145-408 “Untersuchung.” Another work by Gundissalinus on the immortality of the soul was published in the same series by G. F. von Hertling, 1897.
Baur unfortunately failed to note the existence of the De divisione philosophiae in two 13th century MSS at the British Museum in the Sloane collection, nor does Scott’s Index catalogue of the Sloane MSS mention Gundissalinus as their author.
Sloane 2946, 13th century, fols. 209-16, “de philosophia ... auctore Isaaco philosopho.” But the Incipit, “Felix prior aetas qui (quae) tot sapientes ...” is that of Gundissalinus’ treatise. The erroneous ascription to Isaac is probably owing to the fact that the treatise just preceding, at fols. 205-208v, is a translation of a medical work by Isaac. This MS is mutilated towards the close so that the leaves containing our text have the upper right hand corner torn off, thus removing nearly one-sixth of the text. The colophon reads, “Explicit hoc opus a domino Gundissalini apud Tholetum editum, sdens (succedens?) de assignanda causa ex qua orte sunt scientie philosophie et ordo eorum et disciplina.” Similarly in Baur’s text the De divisione philosophiae at pp. 1-142 is followed at pp. 142-44 by Alfarabi’s “Epistola de assignanda causa ex qua orte sunt scientie philosophie et ordo earum in disciplina.”
Sloane 2461, late 13th century, fols. 1-38r, contains the De divisione philosophiae under the caption, Compendium scientiarum, without indication of the author. It also is immediately followed at fols. 38v-40r by De unitate, which Baur found in another MS at the close of Gundissalinus’ De divisione philosophiae, and in a third MS before the above mentioned letter of Alfarabi.
A MS now lost is, Library of St. Augustine’s Abbey, Canterbury, 1175, Gundisalvus de ortu et divisione scientiarum.
Cotton Vespasian B-X, fols. 24-27, Alpharabius de divisione omnium scientiarum, is not the treatise of Gundissalinus, as I was at first inclined to suspect that it might turn out to be upon examination.
Alfarabi’s De scientiis was published in his Opera omnia by Camerarius at Paris in 1638 from a MS which the preface represented as a recent discovery. Baur, p. viii, states that this text differs considerably from the Latin version by Gerard of Cremona, but that the borrowings of Gundissalinus from Alfarabi and the citations in Vincent of Beauvais’ Speculum doctrinale agree with this 1638 text rather than with Gerard’s.
