[255] BN 14704, fols. 144-70 (present numbering, fols. 110r-35v). The handwriting seems to me later than the twelfth century, but I am not an expert in such matters. The text ends at fol. 118v; the rest is tables. [256] Duhem, III (1915), 201-16. [257] CU McClean 165, fols. 44-47, Liber cursuum planetarum vii super Massiliam, “Cum multos indorum seu caldeorum atque arabum ... / ... Attamen siquis providus fuerit premissa satis emendare poterit. Expl. liber cursuum planetarum vii.” The Paris MS ends with the same sentence, but prefixes at the beginning, “Ad honorem et laudem dominis nostri, patris scilicet et filii,” etc. I have examined the Paris but not the Cambridge MS. Duhem does not note the latter. [258] Duhem (1915) 205. [259] Merton College 324, 15th century, but with such early works as that of Marbod, fol. 142, Secretissimum regis Cateni Persarum de virtute aquilae, “Est enim aquila rex omnium avium. ... / ... Explicit iste tractatus a magistro Willelmo Anglico de lingua Arabica in Latinum translatus.” One wonders if it is a fragment of Kiranides. [260] See below, pp. 206, 211.
