[262] Dr. R. L. Poole, EHR (1920), p. 327, does not regard this as absolutely certain but agrees at p. 331 “that the evidence of place and time make it impossible to identify Bernard Silvester with Bernard of Chartres,” as he had done earlier in _Illustrations of Medieval Thought_ (1884), pp. 113-26. [263] B. Hauréau, _Le Mathematicus de Bernard Silvestris_, Paris, 1895, p. 11. [264] Clerval (1895), pp. 158, 173. [265] BN 6415, fol. 74v, “Terrico veris scientiarum titulis doctori famosissimo bernardus silvestris opus suum.” [266] Clerval (1895), pp. 173-4. [267] BN 16246, 15th century. Extracts from it are printed by Cousin, _Fragments philosophiques_, II, 348-52. John of Salisbury in 1159 used it in the _Polycraticus_, ed. Webb (1909) I, xxx, xlii-xliii. [268] Many MSS at Paris, BN 3195, 5698, 6395, 6477, 6480, 7054, 8299, 8513, and probably others. MSS catalogues often ascribe it to St. Bernard. [269] Attention was first called to it by Langlois, _Maître Bernard_, 1893. It has not been printed. A description of some of the MSS of it will be found in Appendix I at the close of this chapter. [270] B. Hauréau, _Le Mathematicus de Bernard Silvestris_, Paris, 1895, contains the text and lists the following MSS: BN 3718, 5129, 6415; Tours 300; Cambrai 875; Bodleian A-44; Vatican 344, 370, 1440 _de la Reine_; Berlin Cod. Theol. Octavo 94. Printed in Migne PL 171, 1365-80, among the poems of Hildebert of Tours. [271] Ed. by Wrobel and Barach, in _Bibl. Philos. mediae aetatis_, Innsbruck, 1876, from two MSS, Vienna 526 and CLM 23434. HL XII (1763), p. 261 _et seq._, had already listed six MSS in the then Royal Library at Paris (now there are at least eight, BN 3245, 6415, 6752A, 7994, 8320, 8751C, 8808A, and 15009, 12-13th century, fol. 187), four at the Vatican, and many others elsewhere. The following may be added: Cotton Titus D-XX, fols. 110v-115r, Bernardi Sylvestris de utroque mundo, majore et minore. Cotton Cleopatra A-XIV, fols. 1-26, Bernardi Sylvestris cosmographia proso-metrice in qua de multis rebus physicis agitur. Additional 35112, Liber de mundi philosophia, author not named. Sloane 2477 and Royal 15-A-XXXII. CU Trinity 1335, early 13th century, fols. 1-25v, Bernardi Silvestris Cosmographia. CU Trinity 1368 (II), late 12th century, 50 leaves, Bernardi Silvestris Megacosmus et Microcosmus. [272] Clerval’s (1895) pp. 259-61, “Le système de Bernard Silvester,” is limited to the _De mundi universitate_ and says nothing of his obvious astrological doctrine, although at p. 240 Clerval briefly states that in that work Bernard takes over many figures from pagan astrology. [273] HL XII (1763) p. 261 _et seq._, besides the _De mundi universitate_ mentioned “two poems in elegiacs written expressly in defense of the influence of the constellations.” These were very probably the _Mathematicus_ and _Experimentarius_, or the two parts or versions of the latter.
